We migrated all the fsmo roles from a windows 2000 domain controller to our windows 2003 domain controller. I used all the tools out there and made sure replication had finished, it was a Global Catalog server, DNS was replicated, and FRS was working. The Win2000 DC has a share on it that our uses access (don't ask...it was set up like this way before I got here). Turns out once we demoted the server, users cannot access the share. I can (I'm a domain admin) and the share has read access for everyone. They get a popup message that says:
"this operation is only allowed on the primary domain controller of the domain"
I'm not sure what to do. I've searched high and low but this error does garner much reaction on a share on google.
