There are versions of RD client that don't work with 6.5. I had that problem on the first Juicy custom ROM I was using. No RDP natively installed, then installed the wrong cab... was for 6.1. Anyway, couldn't connect to ANY of the many servers I manage.

All fixed with correct cab. PM me if you think that's the issue, or search for remote desktop 6.5 cab on here and XDA.

You said your W7 firewall is off and that you attempted via the local IP addy over your wifi network. Make sure you can ping from the TP2 to your local ip. Use pocketLAN. Great utility. There are probably lots of other apps for network troubleshooting from your TP2

Your domain should be your network computer name. In 7 you can find that by right-clicking Computer and choose properties. Computer Name =

2 things before anything:

1) Can you connect to ANY RDP server/workstation using your currently installed version of your phone's RDP client? Possible version issue
2) Can you communicate with the other computer on the local network via wifi ie. ping/transfer files/browse network/etc. Also, some routers have a function that prohibits traffic via wifi to LAN. Only allows traffic to WAN.

Hope that helps a bit.
