Scenario:
Site A (Being Decommissioned):
- DC1
- DC2
Site B (New Data Center):
- DC3
- DC4
Issue:
After building out net new DC3 and DC4 into the domain, and having them joined to the domain and promoted to domain controllers, I have moved the PDC role off from DC2 to DC4; When about to shut down DC1 and DC2, we noticed that when they are shut down any PCs are not able to login to the domain when they are shut off. Long story short, DCDIAG showed a bunch of errors listed below:
- DC1 - Failing dcdiag LocatorCheck PDC Error 1355
- DC2 - Failing dcdiag LocatorCheck PDC Error 1355
- DC3 - Failing Advertising, DSGetName returned info for DC1 when trying DC3
- DC3 - NetLogons failing (Unable to connect to Netlogon Share \\DC3\netlogon, Error 67)
- DC3 - Failing dcdiag LocatorCheck PDC Error 1355
- DC4 - Failing Advertising, DSGetName returned info for DC2 when trying DC4
- DC4 - NetLogons failing (Unable to connect to Netlogon Share \\DC4\netlogon, Error 67)
Any idea on what may be causing some of this and how to correct it so that I am able to properly decommission DC1 and DC2?
