I recently migrated from a Windows 2000 server to a 2008R2. I used DC promo to make the new server a DC, but I haven't yet demoted the old server. All of the shared files are still on the old server with the exception of a few that I am using as a test before I transfer all of the data to the new server. I seem to be having a DNS problem although everything appears to be working fine from the client users perspective.
I'm getting an error when I run the best practices analyzer, "The AD integrated DNS zone -msdcs.domain.com was not found".
I can't edit GPO with the error, "failed to open the group policy object. You may not have the appropriate permissions. The system cannot find the path specified.
When I run DCDIAG I get:
Starting test: Advertising
Warning: DsGetDcName returned information for \\server_1.keystone.com,
when we were trying to reach KEYWEST.
SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.
......................... KEYWEST failed test Advertising
Basically I want to get to a point where the new server has all of the shared files and does all of the DNS, DHCP ect. and just use the old server to store some non-critical easily recoverable files.
