Ok, I have the potential to add quite a number of XP machine to my account. Problem is that for the majority of the day these machines are just sitting waiting for someone to log on. My question is: How can I get these machines to crunch data while sitting on the login screen? Once I have a definate answer to this problem I can take this up with my network admin person. Even though I have administrative privaledges I need to run this by the powers that be. Appreciate any help. PS. We are talking about roughly 50 P4's here. Not a small number.
