Yes NTDoc, this is one of the reasons why I don't like GPO's - the long login time.
Glenn Barnas, you probably get this a lot, but you are brilliant. That is a very good idea. I will test your idea out and see if I can get this to work. You have also solved another problem for me simultaneously with this solution.

Is there any reason why you don't run the scheduled task directly from the logon script. I am assuming that the scheduled tasks are created locally on each computer?

I will get back to you with my hopefully successful results !
