OK, I'm at my wits end and tried just about everything
suggested in the Knowledge base.  5 Windows XP
workstations take between 8 and 15 seconds to open Word
and Excel documents, which all other machines open near-
instantaneously.  The docs were created in Office 97 and
all machines are now running Office XP, and the NT/2000
machines are fine, just the 5 new XP CAD stations.  I've
disabled Oplocks, I've installed SP's and hot fixes,
disabled kernal mode filter driver for Backup Exec and
McAfee, lots of re-boots and no difference.

Performance profiling shows that the workstation is 99%
idle, no network traffic, just waiting for the server to
respond.

Server: Intel Vero Beach, Dual Xeon HT, 1024 GB, 1Gbit
backbone, raid.

Workstations: Tyan Thunder, Dual Athlon 2400, 2048MB, 3Com
10/100, Quadro FX, uSCSI.  All latest drivers and
patches.  The users of these stations are all local
administrators, and I've even tried upping them to domain
admins.

HELP!!!!
