I have an AD integrated forward DNS zone say domain.com. when I try to query a specific record in the zone like ie.domain.com it gives me answer that it's CNAME pointing to www.domain.com.
When I open the DNS Management console, I don't see this record at all.
I cleared the server cache. I created A record with same name and it let me create, but it still continued to resolve to earlier CNAME. I created CNAME record with same name and it let me create, but it still continued to resolve to earlier CNAME.
I also looked at querying the record using dnscmd.exe /enumrecords command I also looked at backend AD location (ForestDNSZone) and there also there is no such record. I also verified there are no conditional forwarder for this domain on the server.
I am stumped right now, from where DNS server is getting that CNAME record?
