Old DNS records that will NOT go away on windows 2003 DC

Hi Guys,

I have taken over the support of an Active Directory from someone else, and have a major problem with duplicate dns entries for work stations which is causing mayhem. I have made sure that DHCP and DNS intregration is set up and working and that scavanging is set up where it should be and reduced the time for records to be scavenged BUT the records still exist. Some IP's have 5 different machine names assosiated with them. I can see that only one record has a current time stamp and all the others for that IP are much older, up to 3 years old.
When I look at the permissions of the older records there is an unknow account, which I am presuming is the computer account which created it, but now does not exist. When I look at the ownership of the record, it is owned by the unknown account.
Before I go merrily deleting records, can someone point me in another less dangerous path or is that the way to go???

I can't see what the issue would be with deleting these records if you're able. Delete the inaccurate records, restart DNS, and see what things look like afterward.

Excellent, I am half way through doing this, and the problem also exists in the reverse lookup zone as well. Strangly enough I have been deleteing records from the reverse lookup zone succesfully, even ones that refer to hosts that don't exist on the domain or the forward lookup zone, all but one that is, when I try to delete it the error returned is shown in the attachement, any ideas???

was scavenging switched on recently ?
you need to give it some time (at least a couple of weeks).

Scavenging has been on for over 3 months, which is why I am concerned that there is some other underlying issue going on....

Sorry to take so long to reply... I had restarted DNS, but did not notice that it had failed to stop! Once I eventually got it to stop and therefore start all was well.
