Well, two more things:
1) You were dead on about the WMI. I restarted WMI on two machines that were giving me problems and they're running great now. I didn't need to delete the directories. Thanks a ton for the help there.
2) If you notice that's where the SendMessage went to, @WKSTA and I will only be running this script locally so that should never be a problem. However, I am looking at tweaking on how this script displays. A console window is ok but I'd like a nice front end eventually for this. Thanks yet again!
