So, I'm having an odd and new to me problem on one of our Server 2003 R2, SE x86 VMs.
The long and short of is that ever since patching last month, we can't seem to RDP into the box, and we do need to from time to time, because it's our Exchange (2003) server, and we occasionally have to administer our mail environment. Attempting to connect over RDP throws a
2308 error code. For what it matters, non-RDP remote connections seem to work fine (PSExec, remote Event Viewer, etc.).
Since it's a VM, I popped on to take a look through the vSphere console, and found the TermService Service to be started, but reverted to Manual
Startup Type, and in a
NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN state.
I changed the startup type, did a
takskill /PID /F and restarted the service, but it's still not accepting connections, and is back in a
NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN state (which is not the state it's normally in), and not accepting connections. Terminal Services Manager shows the two "available" RDP sessions as down, and throws an error if you attempt to reset them.
I have seen references online to this being a result of multiple network cards, but our server just has the one vNIC.
As this is our only Exchange server, rebooting it is a last resort (doubly so because of the red tape we inflict on ourselves around doing so for any server), so does anyone know what's going on, and hopefully have a solution that doesn't involve rebooting?
Screenie below, in case anyone needs the visual.
