I have a domain that is currently running at both 2008 domain and 2008 forest functional level. I have two domain controllers in this domain. One is server 2008 and the other is sever 2008 R2. We previously had a domain based name space running on an old server 2003 domain controller. I have since completely deleted this namespace. However, I am still unable to create a domain based namespace in server 2008 mode. When going through the wizard, the option is always grayed out.
I have double checked my domain and forest functional levels and I have also removed and readded the DFS role to the server without success. I am concerned there may be a gremlin so to speak that is hiding within the directory that is preventing me from creating. Does anyone have any ideas or anywhere I could look?
