I have 2 Win7 Pro computers in a homegroup. I have set up RDC and I can connect from computer a to computer b if I use the IP address, but not if I use the computer name. Any ideas?

Thanks. I have found the cause of the problem. For use when connecting to my corporate LAN thru a VPN, on the DNS tab I have specified DNS suffixes to append to unqualified names.

The computer I was trying to RDC to is called htpc. However, there is also a computer called htpc.xyx.com (assuming one of the DNS suffixes I have is xyz.com).

When I try to RDC to htpc, it tries a connection to htpc.xyz.com, which of course fails.

I found this out by doing ping htpc. The response I got was from htpc.xyz.com.
