I have 3 W2008 R2 Guests running inside a w2008 R2 Hyper-V Host. All three VMs are part of a domain, All with RDP enabled, the machines have the following names and ports
VM1 3401 VM2 3402 VM3 3403
Problem, I can connect to all machines remotely except VM2,"using the domain credentials". I use my.remoteserver.com:3402 to connect to VM2, it fails to login and keeps asking for password (using domain credentials), but if I use the credentials of the host machine (discovered that accidently), which is not part of the domain and has a different password, it logs and in and gets me to the desktop, totally bypassing domain credentials. Yet when I am on the desktop I am actually logged on to the domain.
I also tried RDP from a 4th PC (not mentioned above) on the same network, I login using domain credentials. The problem occurs only when I do this from outside of my network. Obviously there is something in the Host machine that I am overlooking, I have verified and reverified the router and everthing I can think of with no luck, any suggestion would be a great help, many thanks.
