I have four Windows Server 2008 64-bit servers that I use as virtual hosts (via Hyper-V). Over the weekend I did MS Update to apply latests updates and restarted them. Now, for some reason, I can no longer access two of the servers via Remote Desktop Connection.
I used RDC from my Windows 7 laptop and from another Windows Server 2008 64-bit server to access these other two servers before I updated and restarted them so it did work previously. I verified that Remote access is enabled on the two servers and that the correct username / group is specified to access those servers.
When I try to access I get: "Remote Desktop cannot connect to the remote computer for one of these reasons 1) Remote access to the server is not enabled, 2) The remote computer is turned off, 3) The remote computer is not available on the network". Note that I get this message before being prompted for username and password.
One of the servers I can ping via both its DNS name and its IP address. The other server I can't ping with its DNS name or IP Address (get "request timed out"). However, all virtual machines on those servers are working and accessible.
I'm using the /admin switch on the mstsc program though I've tried without it but no luck.
