Really strange. I am able to Remote Desktop over VPN to one of the servers (xxx.xxx.xxx.26), but not to another (xxx.xxx.xxx.27). The servers are on the same subnet.
The funny part is that if I remote desktop to the first server, then I can do second Remote Desktop from there to the other server (the one I cannot access directly - xxx.xxx.xxx.27).
So there is no credentials or login issue I guess. Just something prevents the Remote Desktop over VPN to one of the servers.
Any ideas what might be? I wonder if the number 27 in the 4th octet of an IP has some special designation which conflicts with the VPN.
