Nagios process check simple fix

I'm setting up Nagios for the second time and I'm having to refresh my memory while setting up the service checks. I found a quick fix for one of the template services that always seems to fail - the process check for Explorer.exe. On all of the servers I setup Nagios reported that Explorer.exe wasn't running and was in a critical state. I couldn't see what was wrong with the check initially and that's because at first glance there isn't anything wrong with it. Until you look closer at the process information in task manager and notice that the process for Windows Explorer is called explorer.exe (lower case). It turns out that Nagios process checks are now case sensitive. I tested this with a couple of other processes, testing with upper case, lower case and normal case spellings and this confirmed it for me.
