We are using eTrust AntiVirus so far without issues. We are only running
about 10 users per server at this stage so hard to determine the impact
AV is having. I have had performance issues with Mcafee in the past.
I do think because we have users who only access Citrix it is important
for us to run AV on the server. We simple can't afford to be down
because one user goes to a website and downloads a virus etc.

Subject: [THIN] Yet Another Anti Virus On Citrix Question (hopefully
with a twist)
This is a little long...
I know the topic of AV and Citrix has been beaten to death here, but I
had
an interesting thing happen the other week and wanted to see if anyone
else
had seen anything similar.
Although we are moving to a shiny new Win2k3/MFXP environment, we
unfortunately have to keep the NT4/MF1.8 servers up for another 6 months
or
so. We have barely been able to get more than 65 users on a server
concurrently. Heavy thin client users with published full desktops.
For years we have worked with Microsoft and Citrix troubleshooting BSOD
issues that have really gone nowhere. As a last ditch attempt, I had
one of
our guys completely remove McAfee off of one of the servers in an
attempt to
eliminate yet another variable.
Not only has that one server stayed up for the past 3 weeks but, due to
bringing it back in to the load incorrectly, it also had 94 users on it.
Before we would get 1450 errors and would constantly run out of registry
quota. All of a sudden that one server was handling 1.5 times its
normal
load.
So that got me to thinking - in our new environment I am seeing closer
to
100 users per server, but the memory usage is obscene. Performance is
acceptable though.
Has anyone else ran in to AV software severely limiting the number of
users
you can support on a server? Is it purely a McAfee thing? One of our
new
hires mentioned that they used McAfee where he came from, replaced it
with
Trend, and nearly doubled the amount of users on a server.
I realize my mileage may very, but if I am truly not crazy and McAfee
could
be the root of all of our issues, I am more than happy to look for
alternative solutions.
One last question, do most of you even run AV software on your Citrix
servers?
Thanks!
