Since I have had the Qtek S100 I experience a strange delay when I hook up to my PC with Activesync. It seems that it hangs for around 40 seconds after connection before it recovers and will look for changes. Same whether I use USB or Bluetooth.
I tried deleting the partenership and starting again and this worked once, but I had to hard reset to tidy up and now it is doing it again no matter how often I re-establish the partenership.
Any thoughts ???
sync with dell laptop running W2000P and AS 3.7
upgrade AS from 3.7 to 3.7.1 might help!
I'm using 3.7.1 and have the same problem.

Hi,just turn off your firewall before connecting,I had same problem with Sony P910i called service center and that was the solution.With the S100 had same problem,remembered the issue with sony so I turn off firewall and now works every time.Regards
ActiveSync 3.8 is now available...

Thank's all for your suggestions but so far no luck. I discovered in www.cewindows.net help files that this is a problem commonly associated with the use of Symantec Antivirus Corporate Ed. Ver 8.0. Sometime when I start my laptop I get a message saying Activesync could not initialise....also related.
Unfortunately the company I work for has it installed on all our PCs and they are not planning to update to 8.1 where the problem is fixed.
If anyone has any other suggestions in light of this new info, please let me know.
ActiveSync 3.8
http://www.microsoft.com/downloads/...21-8a85-45a2-8d13-653beb6cdddc&DisplayLang=en
For clarity...I have loaded AS 3.8 and it does notsolve the problem.
You could be having conflicts with the personal firewall installed (XP SP2 or from your antivirus product). See if allowing ActiveSync to pass through helps.
Just checked myself ... Windows Firewall exception for ActiveSync should be on.
Hi
Activesync just decided to stop working yesterday on my O2 XDA Mini S.. I've uninstalled and reinstalled both Activesync and Outlook 2003, and even resorted to hard resetting the device, but I still get a hang when I connect!!!
Any ideas?
Shaun
make a new partenship but do not tick the media box.something to do with media player. i have been having the problem for over a week.
whatever you do do not open media player wile sync as i will desconect the device.let me know how you get on.
I have been having this problem regularly with both my phones since I got my XDA mini S and MDA Vario 2 weeks ago.
I had the PPC6700 for a couple days (switched from cingular to sprint - hated their service so now am back to cingular) now I have the 8125 and with both devices 4.1 blows - very tricky to configure. My issues came from VPN mostly - I say mostly cause it still doesnt like to connect when I have that tunnel in place. What I determined to work on both handsets was sync the cal, inbox, tasks, and contacts with exchange and sync NOTHING locally. If I need to transfer files I do it via mSD card - apps install regardless. This is a high level accounting of what I went through, but will go through more detail if you want.
I had the same problem also some weeks back. It ended up being due to the software firewall I am running (sygate). I've discovered that I have to completely exit the firewall app (rather than just allow all traffic) if I want to sync properly - a real pain!
Based on a bit of hunting I've found out that the activesync connection works by creating a software USB - tcpip bridge. The first step on connecting the win mobile is to assign an ip address to the connection. This proceeds ok with the firewall app running as it works via the normal DHCP port numbers. Once this is done activesync knows there is a win mobile machine connected and starts trying to commumicate with it ( connected..... looking for changes). The problem now is that the communication between activesync and the machine occurs via different ports number *which are blocked by the firewall app*. This also explains why you can't sync when you have a VPN active - the VPN blocks the traffic from the 'extra' local address created by the activesync DHCP request and activesync consequently can't tell the win mobile is attached.
What I don't understand is why if doesn't work when I tell the firewall to "allow all"! There is a document on microsoft's site explaining how to go about setting up a firewall to allow this traffic (google for 'activesync firewall problem'). Problem is that it doesn't seem to work with the sygate firewall as far as I can tell...... any ideas anyone?
does anyone know if you can install IPX/SPX on the handheld?
Hi
Thanks but still not working... I am not running my VPN (I know Activesync never works with my VPN). I do not have any firewall software in place, and the windows firewall is off. My antivirus is disabled when I sync, and I have a valid, DHCP assigned IP address.
I am not syncing media - in fact the *only* item I have ticked is files.
I can explore the pocketpc OK, so I know its physically connecting.
:-(
Any other ideas?

Hi
Sigh, still no luck. So far I have:
1. Repaired and then Reinstalled Activesync 4.1
2. Repaired and then Reinstalled Outlook 2003
3. Repaired mapi32.dll
4. Hard reset the XDA mini S
5. Deleted all partnerships, both sides
6. Changed sync options to only sync favorites
7. Reapplied XP SP2 and patches
8. Removed all firewalls and antivirus software
9. Tried different cables, and IR connections
Yet still, no matter what I do, I get "Looking for changes" forever. Exporing the PPC is fine.
I cannot reinstall XP - this is an company laptop, and MIS do not allow us to reinstall our OS, and as they don't support the XDA, they won't reinstall XP either....
So I'm left with no options - back to a palm!?
Regards
Shaun
Sorted!!
Phew
After random playing I found it... It hangs if "favorites" is n the sync list. If I delete the partnership and when the wizard restarts, untick favorites, it syncs OK.
In all my testing, I had stupidly assumed things like files and favorites would work...
So... I think I'll live without favorites.
Shaun
U must have stuff which is not uninstalled properly. try unchecking everything for SYNC except Files.
I have experienced the same problem. Activesync worked great out of the box, but several days later, began hanging up on "Looking for Changes". Nothing that I tried fixed the problem, including reinstallation, deletion of devices from both sides, syncing with BT, etc. Finally, I gave up and did a hard reset, and Activesync immediately worked perfectly again! I assume that one or more programs I installed on the MDA along the way was causing the problem, and I am now going to methodically reinstall apps until I find the culprit. I will post again when I identify the guilty party.
had the same problems, tried all the standard solutions and nothing fixed the hanging on sync issue...
until i plugged the phone into the usb add-on card instead of plugging in to the motherboard's usb ports.
haven't had any problems since!
Had about the same problem.
Just synchronized once, and on a second connection hung on connecting or looking for changes. Tried everything I could think of.
Last resort was a cold reboot without restoring the backup..
Then synchronizing worked like a charm.
Put back the backup and it still works.
Why? Beats me........
Edit
It stopped functioning again. Have to do a soft reset and delete the partnership on th PC.
Then it will sync for as long as the Wizard stays in the cradle.
When I take it out it won't sync for a second time
Hangs on looking for changes
I find it does this everytime, without fail, if outlook is open when I connect.
If it's closed, and I connect, no problem.
Another quirk is media player.
When the device is connected and you open a movie file in WMP. If you close WMP, the file continues playing (in audio at least). Disconnect the device, no problem.
Works now
Hi,
I had same problem.
I was using Zone Alarm and after I configured it right it worked.
I had to upgrade to pro
Microsoft has got a nice page that explains it for different firewalls.
http://www.microsoft.com/windowsmobile/help/activesync/default.mspx
I do not really understand why it does work now when it didn't when I just diabled the windows firewall or later the ZoneAlarm firewall. But it works now.
Greetz,
Pfeffa-rah
I also had all kind of troubles trying to sync via USB. Now I sync via BT and it works pretty well so far. No need to disable the firewall, no hanging, etc. But I only sync the Outlook stuff, no files or favorites.

First of all you have to open the ports in the sygate firewall like microsoft describes (http://www.microsoft.com/windowsmobile/help/activesync/sygate.mspx)
For getting the synchronization to run with the sygate firewall it seems to be necessary to change the maximum tcp ip packet size (MTU).
You have to change the RNDIS driver settings in the mobile phones registry as well. Use a regedit tool like PHM Registry Editor:
Here are the settings to be added (or to be changed respectively):
Key: HKEY_LOCAL_MACHINE\Drivers\USB\FunctionDrivers\RNDIS
Name of the Value to add: MTU
Type : DWORD
Data: 1514 (Value is Decimal)
Name of Value to add: MaxOutTransfer
Type: DWORD
Data: 1642 (Value is Decimal)
After a reset my Prophet (XDA Neo) synchronized well with active sygate firewall!
had the same problem
I had the same problem when i first got my mda. It didn't even work off the bat. I noticed it was my computer because i tried it at work and it worked perfectly. I called everybody and tried everything you can possibly imagine. In the end i said the hell with it and i reinstalled my OS. Now its working like a charm. Don't what caused it but I haven't had it since.
firewall
I had this same problem and i had to go open up some ports in my windows xp firewall, once i did this, it worked just fine.
if you read the trouble shooting steps that come with the program it tells you that.

I can't perform a sync. My computer recognizes the new device, but active sync just hangs showing a window stating: "retrieving settings..."
Any ideas as to how to fix active sync?
I already tried uninstalling active sync and performing a hard reset on my Exec, but it still end up with active sync hanging.
I have the same Problem and no Idea what to do...
OK, I was able to sync using BT. Now when I connect my Exec using USB, my Exec still won't sync via USB. I already checked the settings if I had the check mark on syncing via USB and I do. I can access my SD Card via USB, but it still won't allow me to sync via USB. Any ideas?
I know I am missing a setting somewhere. Hmmmmm.
OK, another update guys, it seems that active sync allows me to install programs without syncing, so to me this is no hindrance, as long as I can access my SD Card and install applications via USB, it's good enough for me. I guess if I want to sync I just have to use BT. But any solutions on your part is also appreciated.
Hi,
somteimes that's an issue related to firewall or antivirus.
If you're using Sygate or Kaspersky that could happen.
If you use Sygate there's a file in Buzzdev.net to solve the issue.
Hope to be helpful

I don't use Sygate. I do have System Suite with NetDefense Firewall. I'll try and disable my firewall to check if that is what causing me to unable to sync via USB. But how come it allows me to access my SD Card and insatall applications if my firewall is blocking active sync. Shouldn't it be blocking all functions of active sync? I'll post my update once I disable my firewall. Thanks durius.
Hi, it's not the firewall.
BUMP,
I still have this problem.
I had the same problem
1. no Activesync exept the first time
2 no Mailsynch via wireless
3 MSN messenger wouldn't log in
I did a hard reset with the same rom and voila
everything works now.
I jus deleted the wireless remove cab from the xtended rom before the hard reset as i wanted the Wireless Today item back
I also had problems with new Rom , installed ActiveSync 4.1 ,big mistake. Rolled back to 4.0 and now all perfect.

Hi,
I had same problem too after installing i-mate ROM - Activesync just kept saying 'Connecting...'. I went into Device Manager, disabled the Windows Mobile card within network cards, checked for updated drivers (it didn't find any so assume this step is irrelevant) then re-enabled the network card and it all worked like a dream.
Hope this helps.

I had this same issue, drove me crazy. I managed to fix it, but I'm about to be really unhelpful as I din't fix it in a particularly scientific manner.
I was so annoyed that I did the following 3 things, in this order
1 - Went to Device Manager and unistalled Windows Mobile device #X
2 - Uninstalled Activesync build 4.1.41xx, went into \windows\system32 and deleted rapi.dll, then reinstalled version 4.1.40xx something or other
3 - Turned off my firewall
I then managed to sync the phone again, turned the firewall back on. It now syncs fine, but I do still get the msg on the PPC saying "unable to get an IP address"
I sync with two PCs, my home machine and a work laptop. I don't know if maybe I was running two different versions of activesync, but I was able to sync with the laptop even while this was going on.
From what stevegiraffes says, it appears that it was actually step 1 above that fixed the issue. The strange thing was that my PPC device name had been M5000, but after managing to get the damn thing to sync at home it became WM_Ownername again; minor point.
Very odd, but major panic now over
Happy Pi day everyone!

I stand corrected. It was Windows Firewall that caused the problem. I tried disabling both my firewalls again and it worked. Thanks!
Thanks to everyone that responded. I tried all your suggestions, but in the end it was the FIREWALL after all. I am glad this was over.
I just got a new laptop running Vista and I am just having tremendous issue trying to sync my Sprint Mogul (HTC Titan) to Windows Mobile Device Center (WMDC --> ActiveSync replacement in Vista) and Outlook 2007.
Basically, when I connect my Mogul via USB (NO Bluetooth), the device shows that it is connected for syncing to the laptop. But WMDC shows "connecting..." all the time and just not syncing. The only way to do this is to reboot the laptop.
The same phone sync just find to a Windows XP machine. I have tried the following but to NO AVAIL:
- Disable "Enhanced network USB function" in the device (Start -> Settings -> Connection -> USB to PC
- Remove all background services in the laptop, like Anti Virus, Vista Sidebar, Spy Sweeper.
BTW, my Mogul is running WM6, no custom ROM or anything.
Does anyone have the same issue and can provide me with the solution? It seems Vista and WMDC just breaks everything.
what does sync center say?? I'd try going into WMDC and unchecking all the sync content and seeing if it will connect...chances are theres something that it's trying to sync and it won't....I've also ran into a problem recently where outlook must be open for it to sync properly...you can try that.
There are 2 WMDC applications:
WMDC (Start -> Programs): just say connecting
Sync Center (on Taskbar): when I double click, under "View Sync Partnership", it just say "Disconnected"
I always run Outlook 2007 before Sync, so I suspect something else in Vista causing it.
I have tried a fresh Vista install, and it sometimes work, sometimes doesn't.
What I found out is like this:
1) Start Vista and Outlook
2) Connect device to WMDC - WORK
3) Disconnect, but Outlook remain
4) Reconnect - DOESN'T WORK

I have Vista and Outlook 2007 and never had a problem with syncing. I just tried the 4 steps you outlined and it worked when I first connected my Mogul and also when I reconnected the Mogul. What version of WMDC are you running? I have 6.1.6965.
I usually don't run Outlook before doing a sync. I've never had a problem with this either way.
2 Things
I know you said that it shows something about being connected, but have you gone to My Computer and tried to access your device? This will help determine if its just not being recognized by the system properly, or if the sync software is hosed.
Additionally, try searching here or on ppcgeeks.com for the "update vista drivers". I didn't need them - but apparently some folks did. Depending on how long you've had Vista, and/or whether or not you've done M$ Windows updates, I'm thinking your driver could be hosed.
I too have Vista - and I can sync just fine as well as transfer files back & forth through My Computer. I also sync the same device up with an additional computer (how sweet is that? I wish iTunes would freakin' work like that one of these days!) that's on XP.
Would love to help more if need be. I'll be around Saturday if you want to PM and try going over your settings vs mine or something.
Sometimes I have to connect my mogul up to 6 times before it connects properly to my Vista laptop. I now always open device manager before connecting the mogul. It doesn't connect properly until the Microsoft Windows Mobile Remote Adapter driver installs correctly under Network Adapters AND the pocketpc driver installs correctly under portable devices. And it is very wierd because sometimes it works on the first try, and other times like I said b4 it can take up to 6 tries before it works right. I have looked up the error codes that it generates in the Event logs and there are a lot of people who are having the exact same issue, so I chalk it up to a Vista problem and hopefully it will get better after SP1 is released.

How did you get this MS Windows Mobile Remote Adapter and Driver? Windows Update or manual download link?
I don't know how to set my ppc-6800 (same as Mogul) to sync my contacts and e-mails with outlook 2007. When i connect it to my PC, it appears in my computer and i can browse in and transfer files in both ways. But still no contacts or e-mail sync...i would like to get help.

I agree with the problem being a driver issue, mine searches for updates every week. I've had a vista machine since october last year and havent had any problems at all with syncing(usb or BT) or changing roms. As a suggestion when a first got my 6800 in July and switched to the 2.17 rom i had to upgrade to a newer version of WMDC, check your version and the most up to date one on HTC's website. Hope that helps.
Hi all,
I am bringing this thread back because now I have another issue with Mogul syncing to Vista with Outlook 2007. This is actually for my friend but the issue is simply puzzling and I hope anyone have insight on this.
My friend have another laptop and a Mogul and when he connect the device to the laptop via USB, Vista Mobility Device Center (MDC) only recognize it as a MEDIA PLAYER, not as a PDA.
I tried the following:
- Disable/Enable USB Advanced Network functionality (System -> Settings -> Connections)
- Hard reset the Mogul
- Connect the devices and run Windows Update (to check if there is a driver issue)
When I connect that same Mogul to a Windows XP, it sync just fine.
What do you guys think?
Guys,
Just a quick update on the issue whereby I cannot sync the Mogul to Vista: the driver updates did the trick! After installing the driver update, syncing works just fine! I wonder why M$ didn't include this update under Windows Update.
Thanks for the help all!

Please, where did you get the driver updates. Was it a driver on the phone, or for vista.
I am having similar probs, except it appears to sync, but deletes all contacts (inclunding sim!) from my touch dual.
It's shown in the thread above. The driver is available in PPCGeeks. I forgot which thread there, though.

I'm sorry -- was not aware of that. I have automatic updates set up so this question of driver update/renewal never came up for me.
Does this update work for anyone?
My Mogul is hanging on my laptops side...it say "Connecting to Unidentified Device".
And then it just stays there for ever....

The only way I could get around it is to disconnect my device, remove the device from WMDC - and - remove the PC connection in ActiveSync on the device and start ALL over again.
Also, I found that when you have a lot of data (like I do) to start syncing only piecemeal, i.e. do the first sync with the defaul settings first, then add folders, then add emails, etc.
IMHO - WMDC is so inadequate.
Oh well, tried all of these and still no joy
This works for me on my Sprint Mogul a/k/a HTC PPC-6800

Disable the Windows Mobile DNS cache. This requires a registry
modification. Windows Mobile does not include a registry editor, but
free third-party editors are available (such as one from www.phm.lu).
Change the value of:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\InternetSettings\
DnsCacheEnable to 0
If DnsCacheEnable does not exist, create it as a DWORD value.
A soft reset is necessary for the change to take effect.

Hi
Im having a problem with activesync on windows xp. My HTC touch HD will sync with vista at work, but just will not sync on my home pc.
Ive read various threads and some say there is a problem with service pack 3 and activesync 4.5 so I installed activesync 4.2 and 4.1 but I get the same, the computer either reboots when I attach the phone or just will not find the phone. The pc does make a sound as if the phone is attached but activesync doesn’t find the phone.
I noticed in device manager that there is windows mobile device #2 with a yellow exclamation mark and the problem is windows cant load the driver, Ive tried rollback driver, uninstall the item but still no luck.
Im running NRG’s rom but it cant be the rom at fault as the phone syncs with vista.
I will try and take off service pack 3 and see how I get on but if you have any advice it would be welcome.
Thanks
Zeb
No, it's not that.
I have ActiveSync 4.5 on Windows XP SP3 here and my two HTC phones connect and sync with no problem. I have even loaded new ROMs on them from here.
Same thing on my other computer with Windows Vista and Windows 7 with WMDC. No problem connecting with my two phones on any ROM.
Try to clean your USB device list, I had to do this on some computers when a USB device is not correctly detected.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
Delete all keys starting by Vid
I have discovered that Active Sync can't usefully sync with more than 1 or 2 pcs - I too use XP and AS4.2 at home (on a laptop) to sync contacts/diary/tasks - and I hook up to my Vista work PC JUST for power (no syncing whatsoever).
I recently tried to Sync my contacts over to a new laptop, and couldn't do it - I had to copy the Outlook.pst files over and then remove the AS profiles on the phone - very irritating.
Have you tried disabling "faster data synchronization" under settings->connections->USB to PC?
I had the same problem once and removing the tick resolved it...
(Remember to disconnect and reconnect the device after changing this setting.)
Thanks guys for your advice on this.
I formatted my pc and installed windows xp again. I installed my firewall etc and surprise surprise activesync worked perfectly.
I installed service pack 3 and low and behold activesync would not play ball.
So Ive taken off service pack 3. Is there anything critical in service pack with regard to updates?
Thanks Bill Gates for testing your updates.
Working here with SP3 and no 3rd party firewall.
Any 3rd party firewall will block the activesync communication as it's done through IP.
The computer uses 169.254.2.2 and the PDA uses 169.254.2.1
Configure your firewall to allow that traffic
