Hi all,

I am using Windows Server 2003 AD integrated DNS . When a computer fro example PC1 is removed from domain and then add it to domain with different name PC2 . In forward lookup zone , I got two dns host records with same IP address and different names. Some of the application s are not working proporly becuase this IP addresses duplication becuase theapplication got the old name from the DNS.

Can someone please help me how to solve this problem ????

its because the dhcp lease is still present...go into your dhcp options and look for dns settings

For a quick fix open the DNS console / Forward lookup zones / select your domain, find the computer name and delete the wrong record.

Set scavenging of stale records as toniur said.
