I have windows server 2003 running DNS.  I have noticed that DHCP inputs the hostname of the computers that it is giving an address to.  The problem I see is that there are many entries in there that the IP has multiple names kind of like DNS isnt being cleaned out when the address is released.  Is this normal or is there something that I am supposed to do manually every once and a while?

You can either manually clear these records out, or you can enable DNS scavenging to clear out old records automatically after a certain period of inactivity, as described here: http://support.microsoft.com/kb/932464

Hope this helps.

I did not see but will this also clear out records that were manually created?

If an entry has been created manually. it will not be subject to scavenging by default. You can change this behaviour as follows:

- go to view -> select advanced
- right click the record choose properties, and place a check-mark next to "Delete this record when it becomes stale"
