I'm running Windows 2003 DHCP, I need to find out who got what IP going back at least 30 days. Is there a registry setting to increae the retention period for DHCP logs.  I don't what to use reservations.  I believe the default is  for 5 days.

No the log retension seems to be hardcoded to 1 week (possibly one of those undocumented keys).

See this:

If you changed the value to 7 the logs would each be 1 MB in size for each day.  So if you are not getting a full days worth of logs, increase this value.

What you can do is setup a script to backup the logs to a different location.  Another method would be to go into your nightly/weekly backups if you have and navigate the the folder and restore the audit logs (to a different location) and you should be able to find who obtained that IP.
