I have to DC's now, one a 2012R2 (SVR1) and 2019 DC (SVR2). I've added a 3rd one called SVR2A. I am removing AD services from SVR1 because we are going to move it to a 2019 server down the road.
DCDIAG fails just on this one. Passes on everything else. So SVR2a also does not have the NetLogon folders because of this.
Testing server: Default-First-Site-Name\SVR2A
Starting test: Advertising Warning: DsGetDcName returned information for \\SVR1.mydomain.ca, when we were trying to reach SVR2A. SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE. ......................... SVR2A failed test Advertising
Any idea on how to fix this?
