I've inherited the following situation: Two domains with a trust between them, one DC for each domain, both DC are Windows Server 2003 Standard SP2. The previous sysadmin tried to migrate one of the DC's to Server 2008 R2 but had many issues after and none of the hosts could find the global catalog\name server\domain controller. I am very comfortable when it comes to adprep, dcpromo, transferring FSMO roles, etc and don't usually have issues with that. However that all went fine supposedly for the previous guy who tried this migration. Supposedly it was DNS that broke things.
All the DNS I've managed in the past has had a gray color "_msdcs" folder underneath the domain zone. However neither of these 2 DNS servers (1 in each domain) have this.
ABC.Domain1. has the "_msdcs.ABC.Domain1" folder under the forward lookup zone, and no _.msdcs folder under the domain zone.
XYZ.Domain2.local. has the "_msdcs" folder under the domain zone (but it's not gray) and does not have a "_msdcs.XYZ.Domain2.local"
folder at all.
Please advise what they SHOULD look like, and how to correct them.
