I have about 10 Win2008 SP2 Citrix Servers that show the above event logged in the System log prior to the servers becoming unusable and a hard boot is required.. The error relates to the Thumbnail Cache Out of Proc Server COM but I can't find out why it is happening and how I can resolve it. I have approx 10 users on each Citrix Server and their screen just locks up and can't do anything.. even logoff..!

I would appreciate some help in resolving this one ASAP

Hello,

start by running sfc /scannow to check if there is corrupt system files.

If this does not hellp, I recommend performing an in -place upgrade of your OS.

Thanks Mr X.

I did that today and the result was..

C:\>sfc /scannow

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of th
em.
Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log

I don't want to have to do optionB..

Hello again.

Please use Microsoft Skydrive to upload CBS.log.

The corrupted files can be repaired using option B.

Hm got the same prob here :) exactly ;) wath was the solution?

There is a virus hidden in the registry

HKEY_CLASSES_ROOT\CLSID{AB8902B4-09CA-4bb6-B78D-A8F59079A8D5}\localserver32

There is a javascript hidden in a null key. You can delete the content of the key and be done with it. The key is a null value key and Microsoft does not know how to remove it but you can delete the contents

Thanks for info
