DFS root was on a DC which was demoted and formatted.

 

SOX050307700007

DFS was a single un-replicated root. Was previously hosted on a DC which was demoted and formatted.

Points to multiple replicated target links.

The root target data still exists in the CN=DFS-Configuration container (or can be

retrieved from backup).

 

Resolution:

Before attempting to resolve this, make sure you have the latest 2003 DFSUTIL.EXE

(SP1 version is currently latest as of 10-20-05).

1. Back up the DFS-configuration root server leaf object with LDIFDE (it's named

after the old DFS root, and exists in Domain NC | CN=System).

2. Use DFSUTIL to export the data to a text file (/root /export).

3. Stop DFS service on all target link servers.

4. Delete the DFS-Configuration root server leaf object with ADSIEDIT (not the

container, but the actual root leaf object).

5. Create a new DFS root on a new clean 2003 DC (you can use the same name as long

as replication has removed all previous references).

6. Modify the export file to include this new server and the new root share folder

info.

7. Use DFSUTIL to import these settings back in (/root /import /set).

8. Restart the DFS service on the new root server.

9. At this point (using the DFS GUI), you should see all the link targets have been

remapped to the new DFS root (verify your target link replication is still

enabled).

10. In order to increase the availability of DFS in the future, add at least one

more (unreplicated) DFS root target server.
