After installing a new server and promoting it to a domain controller, the replication from the other domain controller did not work and the NETLOGON and SYSVOL folders were not created. Initially, I tried demoting it and re-promoting it, but that didn't work. I found the following Microsoft Support article - http://support.microsoft.com/en-us/kb/315457 - on how to rebuild the SYSVOL tree and it’s content in a domain. In summary, I had to go into ADSI and delete the orphaned GUIDs and create new symbolic links for both of the folders. I also had to recreate all of the group policies in order for them to work on the new server.
