Jim is definitely correct about configuring the AV solution properly,
however, there have been numerous versions from all the major vendors over
the years which have clearly caused issues in Terminal server envirnonments.
These are largely worked out today, but were a problem in the past that were
not just caused by configuration issues....

You're one of the ones I was waiting to hear from Jim. I believe we do have
it configured for inbound scanning only. I won't dispute config errors, but
we seem to be configured correctly here. Our environment is just too fat.

I doubt that is was just trend mcaffee or whatever product. I HIGHLY believe
that it is USER error and misonfiguration of the products along with other
programs causing the issues. It has been my experience with AV products for
example that if you do not turn off outbound scanning it will cause you
issues. Other than that these products work fine on Citrix. We used Mcaffee
for 6 years and now use Trend SMB Officescan client on our servers and it
works flawlessly. People are quick to blame one product over another and
everyone has their favorites. Personally I have found that the trend smb
client uses the smallest footprint, is the easiest to implement and has the
best console for implementing out to workstations as well and controlling
dissemination of updates.

We boot them all every night! All quads. All 4GB memory.
What I didn't want to hear was what you say about Trend. I was hoping that
was my solution!
Crap.

I have experienced problems like this before. Running a farm of 35 NT
servers (terminal server no citrix), and about 40 users per box during peak
times. We would get 1450 errors and would have to remove servers from the
farm. I got to a stage where half the farm was rebooted each night to keep
it running!!
We found once we removed trend AV, the servers would stay up for weeks and
handle more users.
We may have hit a resource limit once AV was installed and could have been
teetering on the edge, however, I still believe it was a trend thread leak
issue but have been unable to get it resolved so far.
I should mention the servers weren't small either, 4Gig RAM quad processor
etc. This doesn't mean anything though when NT has hard set limits for
paged pool and non paged pool memory.

Thanks. We are running 7.1.

Over the years we have seen McAffee cause all kinds of stability and
performance issues. It depends on the version you are using, we are
doing a
large project now with McAfee 7.1 and it seems okay so far....
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
at tempt 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.
