Explorer.exe not running


#1

I’m monitoring Windows 2003 Servers and I get the following error on every server:

CRITICAL
explorer.exe not running

Nagios is running, not other issues except this one.

This error comes up most of the time on most of the servers.

*************** From windows.cfg *****************************

define service{
use generic-service
host_name server1
service_description Explorer
check_command check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe


Any advice would be GREATLY appreciated, I feel like I’m so close, yet so far…

Generally speaking, explorer.exe is only running when a user is logged into the box. I keep a Windows XP machine in my monitoring pool just as a testing point. I’ve got the Alert for explorer.exe set up on it, but disabled notifications because… It kept reporting it in a critical state when I wasn’t logged into the machine. This isn’t to say that someone must be logged into the machine for explorer.exe to be running. I’ve got servers that I’m monitoring that have explorer.exe running that don’t have anyone logged into them. My only guess is that some process that’s running requires some of explorer.exe’s file handling capabilities and keeps it running.
