unable to send CTRL+ALT+DEL and log on

An older SBS 2003 box is locked and CTRL+ALT+DEL does not register.

The computer is usually accessed via Logmein.  There may have been an active session that were disconnected while "Lock keyboard and mouse" was enabled.
The mouse works fine.
I tried the following:
swapped keyboard with another known good keyboard, to a different port.
Tried connecting via RDP, it says the computer is unavailable.
Restarted the logmein service

Is there a way to log off the current user, or otherwise restore access, without forcing a restart?

If it says unavailable through RDP, sounds like its locked up completely.  Is there a reason you don't want to reboot?  That sounds like the best plan.

It would be best to use the shutdown command and force a clean restart. "shutdown \\MACHINENAME -r -t 0" will remotely shutdown that machine.

Since you're working remote (or sounds like you are) make a VPN connection (assuming you have it configured) and run the shutdown command from an elevated command prompt.

shutdown /m \\servername /r /f this will cause a restart and force any applications closed that are locking up the computer.

Log Me In locks up when resources get low to me sounds like an app is eating up memory.

Unfortunately, I don't have the authority to restart the server.  I used the command prompt from another workstation to query the active sessions on the server, and there is only one console session active, which is the account on the server that is currently locked.  I attempted to reset the session and received error 31
could not reset session id 0, error code 31
error [31]: a device attached to the system is not functioning

I will try again after unplugging peripherals, though most posts I have seen related to this error are result of internal drive failure.

I ended up forcing shutdown from the machine, as the system was unresponsive otherwise.
