I read this thread on remote desk top. I am getting the same errors as pc001did.
I get:
"Cannot connect.
Likely reasons are:
1. Specified computer name or ip does not exit
2. A network error occured while establishing the connection

I can connect to my desk top thru my 6800 when it is active syned to my vista laptop. When i un plug the mini usb and try to connect it wount work it just gives me the same error messages you stated. I the following post you stated problem fixed it was the roughter stettings. Please tell me what were the settings . I want to be able to acess RDP thru my evdo connection when i am at work and no where near my roughter. Pleas help this is driving me crazy. again iot works thru my active sync when i am docked with my laptop

Is there somthing wrong with my Internet conn. How do I conn thru EVDO?
