I had thought about that, and there are 0 errors from the firewall, and if it was the firewall, it should affect everyone in every possible combination, not just the TS users.

I did come up with one alternative idea, does not make sense, but...

One of the few differences would be that desktop clients are on seperate subnets than the Squid Server, whereas the TS are on the same subnet.

Will wait to see what the packet capture shows.
