I have an AD Domain with multiple Domain Controllers. Recently the DC tht handled all of the Flexible Single Master of Operation (FSMO) tasks failed. I ran the NTDSUTIL on another DC on the same subnet to clean up the metadata left in AD. During the process the second DC asked if it should take over the five FSMO roles, Domain Naming, Schema, PDC, RID Master and Infrastructure. I passed all of those roles to the second DC. I then re-built the first server, installed updates and now when I run DCPROMO, I get to the point wherer DCPROMO is examining the forest when it stops cold with this message: 'The operation failed because: This Active Directory installation requires domain configuration changes, but whether these changes have been made on the domain controller (<var>varies)</var> undetermined. The installation process has quit. "The system cannot find the file specified". ' I've searched TechNET and everything I've found references prepping a Server 2000 AD for upgrade to Server 2003 or newer. My AD functionality has been at 2003 for over a year. Any ideas to get this server promoted?

Hello, run "netdom query fsmo" and check that all DCs that are listed exist. Sounds for me that one FSMO role is not seized. http://support.microsoft.com/kb/941757/en-us Also make sure to have all references removed in AD database, DNS, AD sites and services etc. from the old one if you use the same name: http://msmvps.com/blogs/mweber/archive/2010/05/16/active-directory-metadata-cleanup.aspx Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
