Terminal server randomly hangs after user logon

Randomly, my users will compliant that when they logon to the terminal server, they'll get the blank screen after entering the username and password.  If they wait for about 10 minutes, their desktop will load but apps will be slow to non-responsive.  When this happens, there could be a few things happening:
1) there's a error message waiting for someone to respond to at the console.  Once someone click ok to the error, everything will be fine.
2) sometime I'll see a message about some user's printer had casue a fault in the printe spooler (very rare on this one) but again once I click ok, everything will be fine.
3) there will be nothing I could do but to reboot the server (sometime hard reboot).  After reboot, I'll see errors like print spooler crashed, hung apps (range from outlook, excel, word, adobe reader, SAP client).

I've been researching this one for a while now but to no avail.  Any help would be greatly appreciated.

Thanks

1. What is the error message at the console that you mention in #1?
2. Have you checked to see if have have bad RAM? You can use memtest86 to do this. There are bootable CD's available to ru it from.

Thanks for your post.
The error message varies.  Sometimes it is one of those memory cannot be read message and sometimes it can be the 'program need to close' message.
I'll have to schedule a time to reboot to run the memtest.  We are a 24x7 shop.  Will get back and report the result.

I would bet it is a printer problem. I have these same type of "random" problems with terminal servers and certain types of printers. What kind of printers do you have? Are these remote users connecting or are these systems internal to your network running as dummy terminals? Have you updated all the drivers for printers the terminal server has connected?

mmcodefive,

These are remote users.  They picked up a lot of printers that don't even have a driver for server.  So, I setup windows to simply not map the printer if there's no driver for the printer at the remote user's location.  Are you still having these problems or have you found a fix for your problems yet?  If you have fixed your problem, please share your solution.  It would be greatly appreciated.

thanks

I have had a ton of problems with printer drivers and terminal servers in general. For example the HP LaserJet 2430. The old drivers were crashing all my terminal servers. What was happening was that the driver was loading twice. The original (new - good) one was loaded already in the TS print server and the old - bad one that the users computer was loading in the terminal print server when they connected. What was funny about the whole thing was that the two drivers had the same name which is the trick to prevent having these type of multiple drivers being loaded. I would definitely check that all your printers are compatible with terminal server, verify you have the latest drivers for every printer, also verify you dont have multiple drivers loaded for the same printer.

One thing that further aggravated my problem was that updating HP drivers to new versions sometimes kept old dll files. Some of these files I attributed to some of my problems. I recommend that you delete the driver from the print server manually then reinstall new.

Done forget to delete the old driver before you install the new driver. Get back to me; tell me how it worked out.

I am trying to schedule this Sunday for this work.  I take it it's best that no user is connected to the server when I delete and reinstall the driver.  I will get back to you.
Thanks

I deleted most of the older driver and reinstall either latest or same driver (but reinstalled) this past Sunday and so far no problem yet.  But the problem I was having was always random anyway so I think I have to watch it for a bit longer before I can say it's fixed.  Also, there were some driver I didn't remove because I couldn't find any driver for it and not sure if any user still needs it.

Thanks for your help.

Did your TS ever crash again? I am having issues again with my HP 2430s.

Sorry I haven't get back to you.  Every since I remove and reinstall all printer drivers (some same one but just remove and reinstall), the server have not crash once (knock on wood and keeping finger cross).  I even left some of the old drivers alone because I couldn't find a newer one or the CD for it.  Maybe the culprit was removed.

Thanks for your help.
