Our third party network/server person set up Entourage on our two Macs to work with the Exchange Server. Both are PowerMac G5 running 10.3.7 on a wired network. Before his tampering, the internet worked great. Speed tests currently show 1346 kbps up and down, but it takes an extremely long time to load pages. You click, the wheel spins for a minute or two on the old screen, then the new page comes up partially loaded and takes another minute to finish loading. The five PCs on the network still run normally - only the Macs he worked on were effected. Any ideas on what the problem may be or how to fix it?
