Both of those are good ideas but then I don't have as much control over when I want things to happen. For example, I wanted to add this in the logon script such that if there is a missing element on the workstation, it would fire off a job and make the required change which requires admin permissions. A set interval will only happen whenever the interval expires. I could live with it but not an elegant solution.

I wil continue my research on this and keep this (or the new thread if you decide to create one) posted for your information.

Thanks again for all the valuable help.
