after moving all 5 FSMO roles from SERVER1 to SERVER2 after a successfull promotion, I am unable to then promote SERVER3, getting the following error:
"The operation failed because:
This Active Directory installation requires domain configuration changes, but whether these changes have been made on the domain controller xxxx is undetermined. The installation process has quit.
"The parameter is incorrect." "
When I open up dsa.dsc > operations masters whist connected to SERVER2 everything seems fine, however doing th same from SERVER1 or any of the other 4 DC's I get 'Error' , I'm unable to transfer roles back as the role holder appears offline, I don't want to seize the roles either as all servers need to stay in use and cannot be permanantly removed as per MS KB's.
SERVER 1 and SERVER2 are both runnning AD DNS.. As far as I can tell there are no new CNAME records etc for SERVER2, hoping this is a simple DNS issue.
