Hope someone can help: Every time I connect my JJ to my PC, I get a popup error message "Pocket PC Networking: Unable to obtain a server-assigned IP address. Try again later or enter an IP address in Network Settings"
This only happens when I connect to my PC via AS, and clearly it's because my JJ is not finding an IP address for via-PC networking - only I CAN access the internet this way! So, it seems that some OTHER adaptor is trying to get an IP address and is failing
I've gone thro all my PPC's network adaptor settings - all set to obtain IP address automatically - but I do believe this problem started when I first looked at these settings.
Is DHCP server enabled on your PC/router/whichever?
No, my PC is not acting as a DHCP server, and my router is an adsl router that serves my PC - which it is doing fine.
I didn't change anything on my PC nor router, just browsed network ADAPTORS on my PPC and next thing I knew I was getting this message. :?
Further, my PPC IS getting an IP address on one of the adaptors, which I can ping from my PC, and it does connect to the internet via my PC without problems (it's 169.254.2.1 on the "remote-NDIS Host" adaptor - which you will show too). Thus, I surmise that the adaptor that is supposed to connect to my PC is working, and it's another network adaptor that's decided it wants an IP for some reason... :? :? :?
Not a critical error, but I hate not being able to solve my JJ problems
I had this problem too.
It's because the Remote-NDIS Host adapter is set to DHCP.
The "catch 22" is this.... If you set it to an IP, the ActiveSync won't connect, but your only other option is to set it to DHCP, then you get this problem.
The solution...
Set Remote-DNIS Host to DHCP via Settings->Connections->Network Cards
Now edit the registry...
HKLM\Comm\RNDISFN1\Params\TcpIp
Edit the key "EnableDHCP" = 0
Problem solved !... No IP set and no DHCP either.
Basically, RNDIS shouldn't have an IP set, but it shouldn't be DHCP either... but as soon as you view RDNIS via the usual network adapters setting then you are forced to have one of the other, which will cause the problem described in this thread or will cause ActiveSync not to work.
Thanks arthurfuxake!!!
You also solved my problem!!!
Good Fix! arthurfuxake

Thatz one awesome soltion arthurfuxake! Thanx man! It seems to have fixed that nagging "Unable to obtain server-assigned IP" error that used to keep popping up on my screen. There is only one other problem... my Atom still can't connect to the Internet through ActiveSync! Any suggestions?!
Hi does anyone out there know of a way i can find out the MAC addreses for the network card on the Qtek 9100 running windows mobile 2005. I need to know the wireless network card and also if the gprs connection has a mac address i need to know that as well.
Thanks in advance.
Barry
why do you need to know this?? :roll:
So i can allow mac addresses only through the firewall

is it like a wireless network your trying to access?
No what we have is a vpn laptop users use securid tags to connect to the vpn and get there email. when they cannot use there laptop to get there mail they use the qtek 9100 create a gprs connection connect to the vpn and get there mail. But they don't like having to use the tag on the pocket pc to connect to the vpn and want it to auto connect every hour and check messages. so if i knew the mac address i could allow them access through the firewall to connect to there mail.
ah right
a bit complex for me... i managed to find mine,.... but only via my wireless router... where i looked in the DHCP active IP table... it has mac addresses in there etc...
I'll see if i can find it on my phone now///
otherwise if you have a few users it might be a pain trying to identify them all eh lol
found it... i think!!
go to start>settings> connections tab>wirelesslan>advanced tab>
in there i found mac address that matches the mac address shown on my DHCP table...
i might be sending you off on a wild goose chase but thats as much as i can find sorry :roll:
Thanks for that but has any got any idea if the gprs connection uses the same mac address or a differnt mac address
GPRS is only virtual, and the radio module has no mac adress. You get only an IP.
But you need a MAC address for the IP to work don't you there must a mac address on the phone would it be the same as the wireless card.
Hi dear developers;
i don't have wirelless modem but i have laptop which has wirelless property i want to share my local internet with my pocket pc. i read some resource but i couldn't achieve it. I do this things... let me know what is wrong?
Create a private network(pcToPc) from wireless networks
i shared it and then i connect it from laptop and i got ip which start with 169... fake ip. so i give manuel ip. i set the default gateway to modem ip. then i can connect to net on laptop but i am not sure the wirelless of the laptop which i shared has internet but i can surf anyway
the pocket pc seems the my laptop's private network i am trying to connect it but it gave me the same fake ip so i give to pocket pc SDIO wirelles adapter manuel ip that's default gateway is same with my laptop (the adsl modem's ip)... so i can get connected but i couldn't use internet. when i am trying to test the intert for example www.google.com after writes locating on status bar then an error "The page cannot be found. Check the name and try again." even thoug i set myISP in network Management -- The Internet.
does anybody understand this connection type? If you share with us we will be very glad. Thank you so much ...
Hi everyone,
I would like to connect to my laptop next room from local network. I can connect perfectly when I type in my IP address into the first textbox (Computer), but I can't connect when I type in my Computer Name (full computer name) instead. I tried MyPCName as Computer, \\MyPCName as Computer, forwarding port 3389 to my IP, leaving domain name empty, putting in my workgroup name as a domain, putting in my computer name as a domain, putting in myPCName\MyUserName as Username, \\MyPCName as Computer, still the same. It won't connect unless I put in the IP address. I would like to do this since my workplace assigns a different IP to my laptop then I assign at home, but naturally I have the same computer name at both places, so I would like to have a permanent setting for both places.
I'm running Windows 7 64 bit on my laptop and 1.66.405.2 ROM on my HTC HD2.
Many thanks in advance.
can you connect to it ok using another computer? might be a dns issue at a guess...
I can connect from other computers fine. Also on my HD2 I can see the host names of PC's under Resco Explorer and map them. However, remote desktop mobile refuses to work with the Computer Name. I can ping my Laptop's IP and also Computer name from pingbox2. Only in Remote Desktop Mobile there is a problem.
windows 7 by default blocks remote desktop connections from different versions of remote desktop. if you right click computer and select properties, then choose remote settings on the right hand side and select the middle option (accept connections from all verions of remote desktop). havent tried this my self but it solves most issues when using different versions of windows
OK, I sort of figured it but would still appreciate some help. Here is how I got it to work:
I had OpenDNS IP under DNS settings for wireless adapter. I deleted them. If I don't do this, pinging my computer name from HD2 always brings 67.215.65.132, which is opendns and not my true local IP, i.e. 192.168.x.x. I also had to disable the data connection (3G) and only have wireless. If I don't disable 3G, I can only connect with IP and not computer name. Only after doing these 2, when I pinged my computer name, I got the true local IP and I was able to connect with Remote Desktop Mobile using computer name. Now my question is:
1- I don't want to quit using opendns, is it possible?
2- I don't want to disable 3G connection every time, is it possible?
thanks in advance.
For me it works with MyPCName in computer and empty domain, both for XP and 7.
Something seems strange with your phone's networking configuration. At a guess (and this is a long shot), I would check your VPN settings on your phone to make sure you're not connecting to a different domain over 3G as this might explain why it works when you turn off the data connection on the phone and why it works by IP address.
As I said though, it's a long shot and is the only thing I could think of that fits your particular symptoms...

about the open dns issues, I suspect that can be solved by making sure your router lets the incoming connection into your home network (you say it resolves to 66.whatever when open dns is used, shouldn't be a problem do long as you don't forget that will be your home ip address so that connection will neef to be allowed through the router and then forwarded by your routers virtual server (our whatever your router software calls out) to your laptops internal ip address.
as for the 3g it should use wifi over 3g by default..... mine certainly does, no need for me to disable it.

I think you're right, when the 3G is on (and also Wifi on), Resco shows computers from all around the country when I click computers near me and not my local network. When only wifi is on I can see my local computers. 3G probably has precedence over Wifi? How can I correct this?

But the 66.whatever address is generic openDNS lookup IP and same for everyone. Are you suggesting me to route this IP to my local IP, i.e. 192.168.x.x? Oh, one more thing, I can also connect when 3g and wifi are both on, but only through computer's IP and not computer name. Can you connect with computer name while both are on and connected?
when your phone does a dns lookup on the name it resolves to the open dns assigned address (not the same for everyone, otherwise the open fns system wouldn't work) so to connect to your computer the phone sends its request to open dns who forward that request to your current actual address.at home that address is your home ip address BUT it isn't your laptops address it is your routers address.(stop reading here if you don't have a router).
so the router needs to be told "if you get a connection request in port (whatever the remote desktop port is) please forward it to (laptop ip address)
its called port forwarding in some routers, virtual server in others.

You're mixing up things a bit - he's not using dns but the computer netbios name. The point is that he has wifi on and connected as well as 3G, thus with an "intranet" ip address on Wifi... so the program/phone should be looking up the name on that connection, where it would find it, instead of looking up over the 3G connection. As the netbios protocol is not routable, it has no chance of finding the computer name over 3G/internet and back home, even with port mappings.

you're totally right, I have a router and its port is forwarded to my laptop IP, but this is only good (and works well too) when I want to connect from Internet to my local network. I tried OpenDNS exceptions for VPN and defined an exception named as MyComputerName but it didn't work. Then I tried a dyndns solution, but it only works for external connections and not local network, i.e. it can't map local IP's. What I need is a dynamic client which can update my local IP.
I also tried to edit hosts entry in the registry with MyComputerName. It works for a single IP, but I'm not sure if I can write multiple IP adresses (my work and home local IP) into that. If I could maybe everything would be OK.
I've just tried a couple of things and it really works fine for me. If I connect Wifi only, I can remote desktop with the computer name. If I then connect data connection, it still works. Disabling wifi and obviously it doesn't work anymore. Re enabling wifi, it doesn't work at first, but does again after ~30 seconds once the netbios protocol has done its host lookup procedures.
There simply shouldn't be anything special to do.

thank you very much for your time, I appreciate it. You're right in that waiting a bit resolves the issue (it's a bit more than 30 secs for me that's why I thought it wasn't working when 3G is enabled) but only when OpenDNS is not used. I assume you don't use OpenDNS, right? Once I put that one into equation, it takes over NetBIOS protocol and returns its IP instead of the local IP(192.168.x.x). As far as I understand, DNS lookup has precedence over NETBIOS and if the name is not found in DNS it consults NETBIOS protocol. However OpenDNS has this nice "feature" where it finds the name with its own IP. There are several posts about this on its webpage and they say to either disable the typo correction or put exceptions for Netbios names, but sadly none of them works for me right now.
Nope, no OpenDNS, never actually heard of it.
How does it work? Do you enter their DNS server address in the network settings of your pc/phone, or is it an app you run?
you click Start/Settings/All Settings/Connections/Wifi/First Button/Switch to Network Adapters tab/Select Broadcom 802.11 DHD Network Adapter/Switch to Name Servers Tab/Type in 208.67.222.222 for primary DNS and 208.67.220.220 for secondary DNS, click OK. that's all. Could you try if it's not so much trouble? Thanks.
OK, remote desktop doesn't work either with the OpenDNS servers in.
I'm pretty sure it must be a limitation of the remote desktop app itself, as resco explorer can still navigate and/or discover the network shares of my other PCs with no problem. NBTStatCE also finds everybody.
Wouldn't even surprise me, as that Remote desktop mobile has always been troublesome. I don't remember exactly, but in the WM5 days it was pretty much impossible to use on a local network due to a weird handling of names... if I remember well all "local" (NetBIOS) addresses without a '.' entered in the remote desktop app would be redirected to the "Work" connection, while "remote" ones with a period would be directed on the "Internet" connection. As a network card can only be defined as one of them, if you wanted it to work in both cases through Wifi you had to switch the card from Work to Internet and back all the time. And of course when it's on Work it breaks some other things that use the default system handling like mail.
So I want to use remote desktop on my TP2 to connect to my laptop at home. I've done all the requirements to allow to use this feature; I've enabled port forwarding in my router settings and I have enabled remote desktop on my laptop's Windows 7 system properties. And on my TP2 I enter my ip address for the "computer" field, my Windows 7 account user name in the "user name" field (I only have 1 account on my laptop and it is admin), and the account password in the "password" field. After all of this, my TP2 will still not connect to my laptop. At this point I am pulling my hair out trying to figure out what I am doing wrong. Can anybody help?
Does your computer has public IP Address?
Yes. I go to www.whatismyip.com and it displays my ip address. I've tried entering this address in the "computer" field as well and nothing.
you'll need to forward port 3389 through any router you may be using (check out portforward.com)
you'll also need to enable RDP connection on the machine through System>Remote.
there are 1001 guides you'll find with a quick google, its not a phone specific thing.
edit: ive previously found that the WM RDP client wont start a 'net connection itself. if you find the same, just do it manually through com manager or check ur mail etc.
Did you forward port 3389 to the internal ip address of your laptop?
Do you have a software firewall on the laptop that may be blocking access?
First try to figure out where the error occurs.
Try to connect to your pc, using an other pc ( from outside )
If it works, it must be a setting in your mobile device.
If pc also doesnt work, it should be a port problem, in that case, try using hamachi..
Oh, and check if you dont have a blocking program, or firewall .. like suggested above
Does my phone need to be connected to wi-fi in order to use remote desktop or will it just use my carrier's data service?

it will use any data connection available, no need to connect to wifi if you have data plan activated.
some tips:
1. you must have NAT (port forwarding) configured in your router
2. If your router has public IP address on WAN port, then point 1. is just sufficient if you are on some routed network, than you need to ask your provider, maybe you will be lucky
2.1. (here are network ranges used as private, only for identification)
from 192.168.0.0 to 192.168.255.255
from 172.16.0.0 to 172.31.255.255
from 10.0.0.0 to 10.255.255.255
3. point 1. specification - enable NAT from WAN port to local IP address of your computer, specific port is TCP 3389. Also is good to make a reservation on DHCP server for this PC.
4. you need to enable remote desktop on your PC
4.1. computer properties - remote desktop setup - and its middle line on remote desktop settings
4.2. click "choose users" and check if your account is listed
Thanks alot to everybody's help! Your advise allowed me to get this things working, I really appreciate it. I had the port open and had remote desktop enabled on my computer but the thing that was killing me was I had the windows firewall on and my ESET Smart Security firewall on as well. Once I disabled them I was able to make the connection. What a head ache those firewalls gave me. I thank you all once again for your assistance.
I want to remotely access my PC from TP2, what software do I need to install on my phone?

The answer depends on what you have available to connect to. Your network (if any exists) and the machine/OS you want to connect to.
If you could let me know the following, I'll see if I can help:
How you machine's connected to the net. (for example, mines something like PC>Router>Cable modem>outside world).
The operating syustem in use on your PC. Specifically please, the edition and version is important to know. Mine's Windows 7 Ultimate, for example.
but, to cut a long story short: if you're not using a home edition of one of the recent windows OSs (XP and later), I'd suggest Remote desktop's the best way to go. There's a .cab knocking around here if you don't already have it on your phone and the PC end's described in the 'Configure Remote Desktop' and 'Configure Your Router' bits of this page: http://www.microsoft.com/windowsxp/using/networking/expert/northrup_03may16.mspx (ignore the other sections, they're not relevant unless you're running IIS)

I have a WIFI Router installed, have a laptop with VISTA ULTIMATE and PC with XP Professional.
I am already able to RD my laptop from my PC.
I want to RDS my laptop from my phone via the same network/WIFI. I think it is pretty simple.
This is what I am doing
I have installed Remote Desktop Mobile
I have connected to WIFI
when I run Remote Desktop Mobile & enter my laptop's name, with username and password and click connect, connecting remains on top and is not connecting it. I am not in any domain, do i have to leave the domain name empty?
if you're not using a domain, leaving it blank's right.
Does it just time out on your phone?
Do you get the same if you try connecting via IP instead of your machine's name?

Your laptop seems to be configured well ( you can access it using the pc )
So it must be a setting in the phone. You sure it is connected to wifi , maybe it stays on 3g ) Or maybe your laptop only allowes 1 ip to connect ( the pc's ip )
I am even able to connect to my laptop over internet as the port 3389 is fwd.
Do I have to configure anything on my phone other than installing that cab file?
Or maybe the cab file I've installed is corrupt or something, can someone please share the cab file?
