Scavenging records - will that delete manual entries?

I've got a Win 2003 AD integrated DNS, DHCP etc.

I have problems with multiple host records for the same IP etc..

I would like to turn on scavenging, although the last time this happened, some A records for non windows systems dissappeared.

I have heard that this should not be happening......is there any other settings I should be looking for?

Scavenging will not delete Static Records.

Scavenging only effects Records with TimeStamps, Static Records don't get these so don't need Refreshing or Updating.

To check the TimeStamp for a Record do View then Advanced within the DNS Console. Opening up the properties for a Record will show it's TimeStamp.

If at any point you issued the command "dnscmd /AgeAllRecords" then you will find the Statically added records are updated with a TimeStamp. That makes the command a poor choice against anything but a purely dynamically updated zone.

Hope that all makes sense.

You know, Chris is right and I am wrong.

I have never had to refresh the records in order to keep them.

But, when I was looking for a link to explain why these records are kept, I found one that misled me in to believing that the records need to be refreshed.

I should have trusted my experience rather that something I read.

Sorry, about that.
