Found quite a number of A records with with same IP in my MS Windows 2003 server. This is my MS AD Windows DC's DNS service. What happens is I got a DHCP server, a Wins server, on top of the dns server. I checked the DHCP console, no duplicates of IPs were given out. I also checked WINs, looks good. Now on DNS, to my surprise, duplicates of A records with same IP. I guess some are the old records (so called stale) not purged, is this assumption correct?
What should I do?
