Hi Jason,
PN on 1.8 srvers uses named pipes for inter-server sharing of the program
neighbourhood info. This makes it extraordinarily sensitive to any netbios
comms issues.
If a server is having performance or other problems, it may not be able to
keep its PN app lists etc up to date. Since PN quries are load balanced,
it's generally good odds that the sick server will be the one replying to
the ICA clients' PN app enquiry.
I suspect that if you make a habit of checking out the least loaded
(according to LBS) server in your farm, you might just track down the
culprit.
regards,
Rick

I talked to citrix and they referred me to document CTX228356. One of the
things they want me to do is perform a 'Qserver /debugnhwatch' on every
server
and compare the output. With 40+ servers and each output 450+ pages, this
is
over 18,000 lines of text to compare. Anyone have any suggestions looking
for
relevant discrepancies using the Citrix Qserver /debugnhwatch utility?
Regards,
Jason

Subject: [THIN] Issue: applications dropping off PN Application
List??
We started experiencing an issue today where some of our applications are
sporadically dropping off the application list (typically from the same
servers). When you Refresh sometimes they will return and sometimes they
will
drop off, however when they are listed they work without issue. Most of the
applications seem to be only published to one server; I'm wondering if it is
an
issue w/ the ICA Browser service. Have tried stopping/starting ICA browser
service on offending servers, rebooting Master Browsers on each subnet and
finally restarting offending servers. Environment: 40+ Citrix MetaFrame
servers, Windows NT 4.0 SP3 using IMS and LBS.
Any ideas would be greatly appreciated.
Can't verify yet, currently workstations are all pushed down the newest
Citrix
client 6.31.1051. I have not been able to re-create the issue from a
published
desktop on the servers, not sure if it is b/c it is a MetaFrame server or
b/c
it has the original client .963.

Jason
