I'm trying to finish cleanup after having to seize fsmo roles from the operations master which failed in our domain. Seizure of the roles went well, Metadata cleanup (MS KB Article 216498
) went perfectly up to item 17, where it says,
Remove the cname record in the _msdcs.root domain of forest zone in DNS. Assuming that DC will be reinstalled and re-promoted, a new NTDS Settings object is created with a new GUID and a matching cname record in DNS. You do not want the DCs that exist to use the old cname record.
I can drill down to _msdcs.root and find the CNAME reference to the defunct server, but can't delete it. When I click the CNAME to select it, the red X in the MMC turns black. Here's a screenshot showing the MMC:
Can anybody offer a possible solution to this?
