Route/Netstat Crashing and/or Ipconfig Not Working = Purple results

["Birney Jr Joe-FJB047" <fjb047 (at) motorola.com>]

Folks,
we have three dell power edge 2950s that are running a Win2k3 OS as well
as the Citrix Xenapp (version 5.0). What we see is that Hobbit will
report the basic test purple (CPU, Disk, Mem, ect) after some time has
pasted. When we logon to the systems we usually see a crash message
saying that either route.exe or netstat has crashed. Checking the task
manger on these boxes shows we can have a mix of netstat and route.exe
still running (some times its just one, other there are 2 or more
instances, or just one of them running, ect). Looking at the event
viewer we will usually see: 
The agent stats generated this event message : failed to execute
ipconfig /all  

But no other error indications on those boxes. And of course when we run
this ipconfig command it works all the time for us. The simple fix is to
kill any an all netstat.exe, route.exe and cmd windows they tried to run
and then the servers go back to green. Problem is they will only last
for some time until they go purple. And the time it takes is random.
Finally we have 6 other Citrix servers all configured in the same manor
that do NOT exhibit this behavior.

So any ideas on how to find out why netstat/route keep crashing?

Thanks!
