Hmmm,

Check your FRS logs and see if you are getting an ERROR_SHARING_VIOLATION on 
that file. Are you using McAfee as anti-virus on your DC? If you are, it may 
indicate an interaction with a low level driver on your DC.

We recently found out (using the GPOTool utility) that a GPO we had changed 
wasn't replicating to all DCs. On two DCs (out of eight), one of the content 
files wouldn't update in SYSVOL. We started the diagnosis process and threw 
just about every common tool at it we could think of to find out what was 
locking it open (e.g. PSFile, ProMon, ProcExp, Open Session files, etc.). I 
even tried to copy a known good copy of the file on top of it manually (NOTE 
THAT THIS IS NEVER RECOMMENDED). Got an Access denied error. We opened a case 
with MS Premier Support and are about to test a resolution. In our situation, 
it appears to involve a low-level McAfee filter driver interaction (this issue 
was recently documented by McAfee on their web-site). Because of the low-level 
interaction, the lock-out doesn't show up in any common utility.

We are currently about to test the following:


Test and implement the NTFS "Install Override" option

http://support.microsoft.com/default.aspx/kb/816493/EN-US/

Also, based upon what we've been told from Microsoft, this change will help 
with 'stuck' GPT.Ini file updates that many GPO Admins run into (mostly in 
large companies and on the domain root GPOs where there are 'many' hits that 
keep these files locked out). Our DCs currently get 'hit' ~ 114,000 day for 
either direct or background GPO refreshes (and that's per each domain-level 
root GPO which has its own GPT.Ini file). FRS has trouble getting access to 
update the GPT.Ini files because of this. The FRS option noted above changes 
the behavior of replication. Instead of being denied access when a SYSVOL file 
is in "read" or "write" state, the SYSVOL file would only be locked out when in 
a "read" state.

What we're hoping is that this changed behavior of FRS will release the lock on 
the content file (GptTmpl.Inf in our case) and then help prevent them in the 
future. If it doesn't release the lock, we know that a reboot of the DC will do 
so (but we'd rather NOT do that). Ultimately, only an update to the more recent 
version of the anti-virus engine will totally resolve our issue, but that new 
version is not expected for a month or two. Sigh...

Darren,

Group Policy Creator Owners have full control on that folder with no deny 
permissions and I still get the same error when I try to apply the policy 
change.

Well, if you don't have any FRS replication issues with SYSVOL, then the 
permissions should be the same on any DC, but I like to use the PDCe for these 
types of things.

Darren,

Thanks!  I will try that.  Do I need to do this on all of the DC's or just the 
primary DC that the GP console resides on?

Scott

OK. Then the next step is to look at the actual files in the SYSVOL part of the 
GPO. Specifically, under 
\\<domain>\sysvol\<domain>\Policies\<GUID<file:///\\%3cdomain%3e\sysvol\%3cdomain%3e\Policies\%3cGUID>
 of GPO>\User\Documents & Settings

Check the permissions on that Folder and the files in that folder (should be at 
least one called fdeploy.ini). Make sure that the groups below have write perms 
on that folder and files and that there aren't any Deny ACEs.

Yes - Domain Admins, Enterprise Admins and Group Policy Creator Owners all have 
the correct permissions.

Scott-
It sounds like someone modified the default permissions on that GPO. Have you 
gone into GPMC and looked at the Delegation tab on that GPO to see who has edit 
perms?

Subject: [gptalk] Group Policy Error

I just started a new gig and my predecessor had enabled folder re-direction 
through the Default Domain Policy.  We are currently having issues with the 
re-direction and I was asked to axe it.  The problem is when I log in to the DC 
and open the Group Policy Management console and try to edit the Folder 
Redirection Policy, I get the following error message:
 Error - Unable to save the redirection information to the configuration file.  
The following error occurred:  Access is denied.
My account is in Domain Admins and Enterprise Admins which are both in Group 
Policy Creater Owners group in AD.  Does anyone know what's going on here and 
how I can fix this?
