WVT as Remote Desktop host can not be connected to

[khonjo]

I set up a Remote Desktop host with x64 version of a WVT and was confirmed able to be connected to. Then I set up another with x86 version of a WVT in the same way, I think, but this Remote Desktop host could not be connected to. The host and the client are in a local network and the same client is used for this experiments. I could not find the difference between the ways these two hosts are set up.

Error message is:

The client could not connect to the remote computer.

Remote connections might not be enabled or the computer might be too busy to accept new connections. It is also possible that network problems are preventing your connection.

I wonder what the "network problems" could be.

The WVTx64 which works and WVTx86 which does not share the same hardware(both OSes are installed in the same box). There are two PCs being the host and the client in the local network and networking operation between these two PCs is normal except the Remote Desktop connection when the host is WVTx86.

Any suggestion is appreciated?
