Users logging in are getting a blue screen and nothing ever happens (MF 1.8)

Hi,

I have three Citrix 1.8 SP4 servers (Win2000 SP4) and one of them is acting very strange. After the users type in their username and password and hit ok, the screen goes blue (like the background) and they never log in. It seems to be hit or miss. If I tell them to log into one of the other two, they log in with no problems. Some users can log in to it (30) are on at the moment, but these users also experience the problem once in a while. Any troubleshooting tips or KB article I can look at? It's getting very annoying. I did notice last week when people were logging on, they were getting an error that Windows couldn't load the profile and to resize the registry MB. After looking at the registry size, it was at 80MB with a 120MB limit. For fun I upped it to 200MB and that message went away.

Thanks,
Matt

Actually it's Event ID 2020. The KB article describes my problems exactly, but says it's caused by Norton AV which we don't use. Any ideas?

This probably applies to 1.8 as well.  You may have some clients that can login if they are running XP.  This seems to usually only effect 2000 pro clients.  

Symptoms

Users connecting with ICA sessions receive a blue background and the Windows GINA does not display after installing Microsoft Rollup 1 for Windows 2000 Service Pack 4 on MetaFrame XP and MetaFrame Presentation Server 3.0 servers.

The console might be unresponsive and have high CPU utilization within the winlogon.exe process.

Cause

The issue occurs after applying the Microsoft Update Rollup 1 for Windows 2000 Service Pack 4 (Microsoft article 891861) to MetaFrame XP Feature Release 3 Service Pack 4 servers and MetaFrame Presentation Server 3.0 servers.

Solution

The issue has been, or will be, addressed in the following Hotfix Rollup Packs. Download and install the appropriate fix for your platform.

Hotfix Rollup Pack XE104W2KR01 - For MetaFrame XP 1.0 for Windows 2000

CTX106619 - Hotfix Rollup Pack XE104W2KR01 - For MetaFrame XP 1.0 for Windows 2000

For all versions of Citrix Presentation Server install the Update Rollup1 for Windows 2000 SP4 (Version 2). You can either remove the Update Rollup1 for Windows 2000 SP4 Version 1 (The older version of this update is (20050602.215753) or you can install the new version number Update Rollup1 for Windows 2000 SP4 (Version 2) (Microsoft version # 2050809.32623) on top of the version 1.

To access this software, visit http://support.microsoft.com and reference KB891861. The file name for version 2 of the Update Rollup1 for Windows 2000 SP4 is Windows2000-KB891861-v2-x86-ENU.EXE.

Instead of messing around with even more patches I performed the steps below on all of mine and my customers servers and this fixed the problem  I have performed this on many servers without causing any other issues.  You must restart the server to have this take effect.  

WORKAROUND
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this problem, follow these steps:1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and click the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Citrix\Ctxhook\AppInit_Dlls\Smart Card Hook  
3. In the right-pane, locate and double-click the FilePathName registry entry.
4. In the Value data box, locate and rename scardhook.dll to scardhook.dll.old.
5. Quit Registry Editor.
6. Restart the computer.

I haven't applied any patches or updates to this server since July 4th of last year. I'll try the second suggestion with the registry and see what happens. This server reboots on Sunday mornings so I'll let you guys know on Monday.

Thanks

Ok,

I was going to change the registry setting and I don't have that key. Actually, after HKEY_LOCAL_MACHINE\Software\Citrix, I have no Ctxhook. Any ideas?

Thanks

The registry setting should only help with the ms rollup 1 problem.  I don't think I would change the registry key if you are sure the rollup has not been applied.
