Hi Rob,

This may sound stupid, but I had this problem on Monday and Tuesday in a
clients site and it turned out to be the Sasser worm infecting one of the
file servers on the same switch as a couple of MF servers. Same symptoms as
you.

Subject: [THIN] Published app not working sporadically


I've got a strange one for the experts... I just completed migrating my
NT4-MF 1.8 farm (27 servers) to W2K3-MFXPe and we are experiencing a
peculiar problem. Twice today the main published application was no longer
working. Message said could not connect to Citrix Server, but other "hardly
used" pub apps were working fine. It was only the main pub app that was
dysfunctional. The ZDC looked good, IMA running, CMC showed 2200 users
currently connected to the pub app but no new connections could be made.
This  behavior remained for about 20 minutes or so both times it occurred.
The first time in the day was not particularly heavy usage but the second
was a heavy usage period (5:00 - 5:30 PM). After checking event logs and
server performance (nothing notable), all seemed fine again. Any clues? Any
ideas where to look for issues when (not if!) this occurs again?

Thanks!!
