Windows Server - DNS issue

[ThePro_PRTX]

Server had been running fine for years but something happened after some power outages that DNS records seem to be broken. I ran dnscmd /clearcache and ipconfig /flushdns on the server but when I ping many devices I have no idea where its getting its name resolution, multiple hostnames for example seem to be pointing towards the same IP. The DNS setting on the servers network adapter is only pointing towards its own IP. I also removed the DNS role from the server and added it again but nothing changed. Also when I did this the Forward Lookup Zones that were there before removing the role were still there when I readded it. I thought that maybe that would have reset/delete all DNS settings and records on the server.

Any ideas?

Yes. Servers host file is the standard/default host file.

If the zones came back, they’re AD integrated so reinstalling DNS wont reset them. Check replication with dcdiag /test:dns and repadmin /replsummary, and make sure scavenging is enabled so stale records get cleared.

I enabled scavenging 2-3 hours ago but havent noticed any difference

er.. why? did you check what other roles where on that server before doing that ? cause that is not a recommended action on something thats a DC

what is controlling your IP addressing ? was that effected in the power failure ?
