Hi
Ive been having major GPO problems and picked up that we have some morphed foders, so in the policcies folder i have
 
> Sysvol\domain.com\Policies
> Sysvol\domain.com\Policies_NTFRS_xxxxxx

as well as

> Sysvol\domain.com\Policies_NTFRS_xxxxxx

So the folder is renamed but there is no original folder. I know how to resolve the issue with the "good" and "bad" folders but in the other case i just have the "bad" folder, what do i do to resolve this?

Thanks
D

You can reinitialize FRS on that one server.

There are two methods:

1)  Non-Authoritative.  
2)  Authoritative.

This artcle describes both methods.

http://support.microsoft.com/kb/290762

I would start with the Non-Authoritative (D2) method on this one server.  Create a Policies folder beforehand.  You could copy the contents of the NTFRS_xxxx folder into it also if you like.  Stop the NTFRS service before creating and copying the data.

If that doesn't help, then you must D4 the good server and D2 the one that was missing the Policies folder.

Let us know.

Do you have a server that doesn't have the NTFRS folders but does contain a Policies folder that has as many objects in it as there are Group Policy Objects in GPMC?

If so, use that one as the good one.

I want you to start with the bad server and a non-authoritative FRS rebuild - that's a D2 on one server.  If that cures the problem, go no further.  Otherwise, go with a D2/D4 approach.

sorry ive just relaised i made a mistake in my intial description.

Its actually more like
> Sysvol\domain.com\Policies\{Policy}
> Sysvol\domain.com\Policies\{Policy_NTFRS_xxxxxx}

There are 3 morphed folders in here with no corresponding original policy. Hope that amkes more sense?

There may have been (or still is) a replication problem with these servers.  One or more policies were added or changed while the replication wasn't working - and from all the DCs.  Once replication started working these folders would have been created due to collisions.

Pick a server.
The Policies folder should contain GUID folders without the NTFRS added to them.
Stop NTFRS on all servers and fix one of them so there are no FRS collision folders on it.
This is the server that will be the D4 server.
Delete the contents of all the other server's Policies folders.
All others will be D2.
Restart NTFRS on the D4 server - wait one minute.
Restart NTFRS on the D2 servers.

You might want to cut and paste those folders somewhere else temporarily so we can retreive them if necessary.

We have 50 DCs and ive checked most of them and they all have the same 3 morphed folders, i dont think there is  a dc without the 3 morphed folders.

50 DCs....wow.  That's gotta hurt.

Are you able to script something to determine if any of the contents across theses 50 servers is different?

it does but we are planning on doing some consolidation over the next few months. I can try sctipting something but might take a while seeing as i havent written something like that before. might be faster for me to check them manually.

I renamed the offending folders _bad., waited for replication and now ultrasound gives my sysvol a green health rating. Im assuming all is well again.
