Ok this is driving me crazy. If I interpret correctly the line "Available RID Pool for the Domain is 3106 to 1073741823" it should mean that I've not exhausted anything at all!!! Am I reading something wrong?
After P2Ving a DC dcdiag reports "name unavailable" for its own ip address
We are in the process of upgrading our Server 2003 R2 infrastructure to 2019. Just before trying to take the migrate path, we had to P2V the existing two DCs to ESXi, since we were afraid of the physical hardware failing.
Specifically we've offline P2V'ed srv2 having ip 192.168.1.13 (the other DC srv1 is at 192.168.1.12). DNS forwarders for this network were 172.30.47.4 and 172.30.47.5. We've run a couple of hiccups during the conversion, but essentially all went well. Replication works fine and dcdiag /test:dns /e /v as well as repadmin /replsum /bysrc /bydest /sort:Delta pass without issues.
We do have one question though. Running dcdiag shows a "name unavailable" next to the ip corresponding to srv2:

Any idea on what to look for? If needed I can paste the entire dcdiag output.
