I maybe answering this question myself but if i want to delete a Server 2003 R2 namespace - do i just open DFS management  and right-click the namespace and delete?

Do i need to do any checking or prepping before, or any gotchas i need to be aware of?

There are two nodes in AD which store the information of the DFS Namespace:

Node1. Store the DFS Namespace information which shows under the Namespaces node in DFS management console. CN=DFS-Configuration, CN=System, DC=Domainname, DC=domainsuffix

Node2. Store the DFS Replication group information which shows under the Replication node in DFS management console. CN=DFSR-GlobalSettings, CN= System, DC=Domainname, DC=domainsuffix

ON a DC use ADSIedit.msc to delete the orphaned namespace information \domain.tldDFS_Namespace under the node CN=DFS-Configuration.

1. Launch ADSIedit.msc

2. Connect to "Default naming context" (the domain partition)

3. Expand and locate to the following node:
CN=Dfs-Configuration, CN=System, DC=ourdomain, DC=tld

4. Check if the orphaned namespace CN=DFS_Test is under it, if so, you may delete this node CN=DFS_Test

5. Afterwards, please run "repadmin /syncall" if there are multiple domain controllers in the environment

6. Then run "dfsrdiag pollad" on all the DFS member servers to manually make them sync the information from AD database.

Then, you may launch the DFS management console and then right-click on the orphaned namespace, and then select Remove Namespace from Display… if needed.


After these steps you can proceed to re-create your DFS Namespace. When creating the Namespace you may receive the error: “ The Server you specified already hosts a namespace with this name. Please Select Another Namespace or another server to host the namespace.”

If that occurs:

1. Stop the DFS service by tying net stop dfs at a command prompt.

2. Delete the following three registry keys/values:
HKLMSOFTWAREMicrosoftDfsRootsDomainYourOldNamespace
HKLMSYSTEMCurrentControlSetServicesLanmanServerSharesYourOldNamespaceShare
HKLMSYSTEMCurrentControlSetServicesLanmanServerSharesSecurityYourOldNamespaceShare

3. Reboot the server and restart DFS Service.

4. If it still appears, delete the Namespace from the Display.

5. Proceed to recreate a Namespace.
