DNS DUplicates |
|
|
Looking thru my DNS I noticed that different DNS records of computers have
the same IP address-is this normal and do the old outdated entries go away
after a period of time? Or is there some sort of error in my DNS?
Using Windows 2003 servers. |

Sounds like you need to enable DNS scavenging. Scavenging cleans up stale
dynamic resource records by deleting ones that haven't been updated within a
specific interval, by default is 7 days. (the actual time to deletion is
longer, but for simplicity, if the record isnt updated for 7 days its
considered stale).
You need to enable scavenging on the actual DNS zone, then you will need to
select one DNS server to perform the scavenging of the records. Get the
properties of your zone in dns (company.com), on the general tab press the
"Aging" button. Check the box that says "Scavenge stale resource records".
Now select the server you want to be the scavenger, in DNS manager get the
properties of that server, select the advanced tab, check the box at the
bottom "Enable scavenging of stale resource records"
