Unfortunately you'll get no answer. From nobody. And downloading something from somewhere is too insecure for me.Please clarify what's your real problem, what have you tried so far?Debugger?Exception?Google? With Regards

A few suggestions . . .

Can you connect to your RDP server using any other RDP client (not your WP7 app)?

Is Windows Firewall (or any other firewall) blocking inbound connections on the RDP port?

Are you using the standard RDP port? If not which port is configured?

Have you tried putting Wireshark on your RDP server to see if packets from the WP7 app are even reaching the server?

How do you connect to your RDP server? Over the internet? Is it behind a router / firewall? Do you need any port forwarding set up? 10.x.x.x is a private IP address, so shouldn't be directly reachable from the internet without some sort of forwarding from the public side of your router.

Can you add anything to your code to give you a more detailed error message?

I can connect to the @ IP using a standard remote desktop of Win7
and firewall not blocking the connection
Yes I use the standard RDP port 3389
I try to see if there any connection using fiddler2and nothing happen
I connect to the RDP over internet, and there a firewall and fixed @ IP
I use the original app and its work great and I can connect to any PC over internet

OK - so is your Win7 connection going over the internet? Or is that an internal / LAN connection only? If internal, is there any way you can test it externally over the internet?

I think you are saying that your WP7 app can connect over the internet to other RDP servers - so it is just the connection to your own PC that doesn't work - is that right?

If so, what is the external / public (fixed) IP address on your internet connection? That's the IP address that you need to connect to if you are connecting from WP7 over the internet. Your firewall / router should map a port on the external / public / internet side through to the RDP port on your PC that sits on the internal side. Presumably the 10.x.x.x IP address is the INTERNAL IP address of your PC - so known only to devices on the internal LAN - and never directly accessible from the external / internet side - which is why you need port forwarding set up on the firewall / router - e.g. public / external address 88.89.90.91 port 3389 mapped to private / internal address 10.11.12.13 port 3389 - note also that the public and private port numbers don't necessarily have to be the same either - this is something you can configure - and for RDP we are talking TCP only here, not UDP.

Apologies if any of this is just telling you stuff you already know, but from what you've said so far this sounds more like a routing issue than a code problem.

Yes I know all that
its a LAN connection, and I try test over another connection using 3G key, just same error
I connect from my PC using WP7 emulator to another PC (different @ IP)
me too thinking of routing problem

NuttingCDEF 6-Apr-12 11:40am

3G key will go via internet / your external IP / router etc. But that doesn't explain why direct LAN connection isn't working. I think the video showed your WP7 emulator connecting - so if it works to another PC on your LAN and not to your PC then the issue is your PC.

If emulator is running on same PC as your RDP server then have you tried connecting to loopback (127.0.0.1) or localhost? Never tried it, but maybe worth a go.

What options did you pick to enable RDP connections to your PC? What security / authentication options? What does your client use? Any issues over encryption of the link? What do the server / client require / expect?

You say you've used a packet sniffer and there are no relevant packets being detected. If the WP7 emulator client and server are physically on the same PC that might be a red herring. Can you try it over the LAN (preferably something very simple - 2 PCs hooked up to a router / DHCP server with nothing else connected?) between 2 separate PCs? Can you then check at both client and server end to see what packets are being sent / received?

OK that's what my mentor tell me, and we try it, I setup net monitor of Microsoft on server and I find some problem, I will get e screen capture and I will post it here
when I try to connect with the original app I find that app send request value "A" and receive value "S" and repeat one more then the RDP connection started
but with my app there is no RDP connection and repeat the send/receive 3 times for 1 minute then it end with value "F"

juste_3al_faza 10-Apr-12 5:45am

I upload some videos using monitor traffic :
the original RDP

Showing my error

You see the difference between he 2 apps, it's the send the RDP started from the 4th line
