Take a look using NT Filemon to see what the problem files are, this
will help isolate which program is causing the excessive I/O. For
example the MS Office Save dialog autocomplete does a complete file scan
of the recent docs folder after every character that is typed. It could
be a single user with thousands of files in this folder and it takes
them several minutes to type in the filename.

Be careful about using Filemon on a busy server, make sure to disable
autoscroll and set the priority low.

No memory constraints or processor bottlenecks.  We have been trying to
track down processes and see that Winlogon.EXE and Services.EXE do a ton
of writing, but looking at other servers it seems to be normal.  We have
tried removing AV from 1 server to no avail.  Servers are patched and
latest BIOS and Firmware is applied.

Recently we started experiencing extreme % disk utilization problems on
all of our servers but 2.  The hard drive will spike at 100% for minutes
at a time.
