A common task for I.T. people is managing updates for their Windows servers and workstations.  While WSUS is nice, free tool it does lack some advanced reporting.  Another issue is that if a workstation or server hasn't ever contacted or isn't using WSUS, you can't get a grasp on it's status.

There have been many occassions where I've needed to check for a given value within an array in VBScript. There's no built-in function for this, so I crafted my own.
