Working on an ISA server the other day I had to change the LAN IP addresses. I was RDP’d into the server from the internal network when I made the change and applied it. I waited a few seconds and tried to reconnect to the server (by name). DNS has updated properly with the correct IP address, and I could ping the address, but I couldn’t RDP back to the server. The server was virtual, so I used VI to connect to the server console. I didn’t see any issues, but rebooted the server to be sure. When the server came up, I still couldn’t RDP. I checked the Terminal Services service and it was not running. I tried to start it, but it failed. I checked the event log and it mentioned something about the service binding. I ran the Terminal Services Configuration console, checked the Properties of the RDP-Tcp object. On the Network Adapter tab, the “All network adapters configured with this protocol” was selected (which is the default, but wasn’t working). I manually selected the LAN NIC and hit Apply, and RDP started working again. [more]
