>To add to what Wayne has said, Evan, have you tried completely removing the AV on the Acer clients (or one of them, anyway), just to be sure the AV is not somehow related?

WHen I exit out of the virus scanning software, the problem still happens. I noticed in the task manager that there were a few anti-virus processes still runing. After killing those, problem still happens.

I could uninstall the anti-virus software, but I would get my hand slapped big-time and it would take weeks for the help desk to send someone over to reinstall it.
