I'm trying to promote Windows 2008 R2 server to a DC and am getting the following error part way through:
'fatal: dcpromo_joindomain: the server was not promoted to a domain controller' however I have this to add:
"You cannot install an additional domain controller at this time because the RID master %computername%.domainname.local is offline"
The FSMO role holder is an SBS2011 server. There is also another 2003 DC. Everything seems to be communicating fine.
