Hi Sean,
You are a champion in many ways. One of my customers is also getting these
events on their Windows 2000 Citrix servers, and it's been driving my nuts
researching what has caused it. I am convinced that it was a hotfix such as
the MS06-040 and MS06-042 security updates. These patches have received
quite a bad rap on other forums. The problem is that I'm not sure if it's
the Citrix servers or their Windows 2003 file server that is causing the
issue. They have already applied the patch you mentioned to their file
servers. Unfortuntely they tend to just apply patches without testing
first. So these security updates have been applied to all Citrix servers.
They are also having other issues where users sometimes don't get their
drive mappings and/or group policies don't apply. When that happens the
following messages appear in the event logs.
Event ID: 1000
First event: 08/14/2006 13:37:34
Last event: 08/14/2006 13:37:34
Source: Userenv
Type: Error
User: McgowanP
Log: Application
Computer: TSP05
Description:
Windows cannot query for the list of Group Policy objects . A message that
describes the reason for this was previously logged by this policy engine.
Event ID: 1000
First event: 08/14/2006 13:37:34
Last event: 08/14/2006 13:37:34
Source: Userenv
Type: Error
User: McgowanP
Log: Application
Computer: TSP05
Description:
Windows cannot access the file gpt.ini for GPO The file must be present at
the location <>. (). Group Policy processing aborted.
I haven't found a DC that is missing the gp object. But I've got logging
enabled in every which way to try and get to the bottom of this.
Keep in touch on or off list. I am seriously considering getting Microsoft
involved next week.
Cheers.
Kind regards,

[THIN] Event 50 and event 26

Please respond to

This week I've ocassionally been getting errors 50 and 26 on a small
Citrix farm. The errors occur on three of the four servers (Win2000,
XPa) for one specific application. The applicatgion is published to all
server though.
Some background: a new file Windows Storage Server (64 bit) with latest
patches was introduced. File migration from the old (Win 2000) file
server initally seemed good, but then I found that users were reporting
errors for this one specific application.
The symptoms are described here:
http://support.microsoft.com/?kbid=890352
Obviously I can't apply the hotfix mentioned in the article to the
Citrix servers as they are Win2000.
The Citrix server that doesn't have the issue *doesn't* have a mapped
drive to the working directory (J:) of the application (an oversight on
my part when I remapped drives to the new file server). Also worth
noting is that users login scripts map to the application folder (J:)
I've moved all the users of this app over to the server the "good"
server. I'm now considering the idea of disconnecting the J drives on
the other Citrix servers. However the above KB article states that
"Note This problem does not occur when the program writes to a volume
that is connected by using a drive letter mapping." which is the
reverse of the situation I have!
Any pointers much appreciated.
