I tend to agree with Roger. Just to give you "peace of mind", if you can manage the switch, check to see if you run across any FCS or align errors, or large amounts of small frames called "runts" on the ports that connect to the exchange server. This would be indicative of a duplex mismatch or a faulty nic.

No luck. We have Compaq NICS - both forced to 100 full and confirmed compatibiliy from Compaq corp. Thanks again for the thoughts.

First, you don't state what (if any) antivirus software is running on the machine. There have been issues in the past of AV causing this kind of slowdown, but if its one of the better vendors you're probably fine. Second - my guess is that you're having network problems, specifically the NIC to Switch connection is set to autosense, which is BAD. Force both the switch and NIC to 100Mb Full Duplex and see if that fixes the issue. If not, try 100/Half (some NIC drivers can't handle 100/Full correctly).
