For 2003 domain with XP clients...Many 5805's  are recorded in the DNS system event log.  When I connect to the machine that is flagged via RDP or Pcanywhere the machine name that I am connecting to is different that the one recorded in the DNS system log Two differnt nmaes are pointing to one IP.  Is it necessary to match up DNS scavening with WINS extinction?

In my experience Scavenging works best when set to match with the DHCP Lease Time. That is, when both Aging Intervals are added together they are equal or slightly greater than the lease time.

For example, a DHCP Lease Time of 10 days will work well with a No-Refresh Interval of 6 days and a Refresh Interval of 4 days.

This keeps replication traffic for DNS relatively low, while keeping DNS clear of clients which only leased an address once.

Remember that Aging Intervals are set per-zone, and it won't do any good at all unless you set Scavenging to run on a regular basis from the Advanced Properties of the DNS Server node in MMC.

Same applies really, Aging intervals so a record will become Extinct when the DHCP Lease is up.

There will still be a certain amount of clutter caused by IP changes, this should at least help minimize it.
