One guess is that that is a GUID for a client side extension DLL. I was not
able to find any reference to that specific GUID under
HKLM\Software\Microsoft\Windows NT\Currentversion\Winlogon\GPExtensions but
you might check your systems to verify.

Subject: [gptalk] Trouble Shooting Possible GPO Problem (long explanation)


I have a group of computers at one of our locations and they are throwing
UserEnv errors. The error message that I am getting appears to be the


"Windows cannot query DllName registry entry for
{F6E72D5A-6ED3-43D9-9710-4440455F6934} and it will not be loaded. This is
most likely caused by a faulty registration."


I browsed through my policies \\domain.com\SysVol\domain.com\Policies\
<file:///\\domain.com\SysVol\domain.com\Policies\>  and I was unable to find
a reference to that specific GUID. So I did the next thing I could find and
I punched in that GUID listed above into the registry and it came up under
the following section in the registry:


HKLM\Software\Microsoft\Windows\Group Policy\History\<GUID>\3


Under this key I have the following entries: Display Name, DSPath, Extension
(A list of GUIDs with the matching one from above in the application log
error), FileSysPath, and a whole bunch of others. including one that says
GPOName which refers to another GUID. This GUID I CAN track in the Sysvol
folder and the GPT.ini says the displayname=New Group Policy Object of which
I have about 4 of these and they seem to be unlinked through out the domain.


Ok now that all that background info is out of the way. I have a feeling
that this UserEnv error being thrown has to do with really long login times
by the end users at this location. The GPT.ini gives me a valid name of a
GPO that we are using however: 1) it is not linked and 2) of the 4 GPOs with
the name "New Group Policy Object" not one of them has a GUID that matches
the one listed from the registry (GPOName entry). I want to get rid of these
errors to remedy the long login time issues. Where should I start? Should I
just delete all of the "New Group Policy Object" policies from the domain?
They don't even seem to be linked anywhere.


Thanks for any help!
