Terminal Server/Citrix - dropping connections

[snootalope]

Hello

Software:
Windows 2003 Server w/SP2
Citrix Presentation Server 4.0
Clients/Users: Wyse Winterm S50

Recently, user sessions have begun dropping for no apparent reason. They're clamming things seem to begin to slow and then they're back to the connection manager of our wyse terms, where they have to reconnected and are brought right back to their sessions that was just dropped.

We've never had this problem before, and I can't think of anything recently, network related, that's changed. Other than applying SP2 on windows 2003.

This is happening to both LAN and WAN users just the same so I really don't think it's a bandwidth issue. There's no errors anywhere! nothing in the event logs and nothing on our routers and switches.

I have our ICA keepalive set to 180 because of a particular slower WAN office, but that's been set to that for six months now, so I don't think it's that either.

Anyone got any ideas? Anyone got SP2 on their Citrix boxes?

Thanks for any help!

I updated 4 of our TS to Windows 2003 SP2. SO far, no issues. Sounds like a network issue. I would keep an eye on your switch that the TS boxes are connected to. Maybe there are some bad ports that are dropping connections sporadically? Just a thought.

Actually, I've found the cause.

I didn't have any rollup packs or hotfixes on our machines before the SP2 upgrade.

Anyway, if you've got RollUp pack 03 and Hotfix 050 - you're good.

Here's a link to the citrix forum with all the answers:

PGaliardo - what rollup's and hotfixes do you have? What version of Citrix?

Snootalope,

We are on PS 4.5 with no rollups yet, so I assume this problem was resolved in 4.5. Thanks for the link though.
