DHCP server history or log ?

People,

Is there any Windows Server DHCP log or history about what IP address was used by certain computer ?

I need to backtrace the IP address used by the computer which is no longer available in DHCP.

Thanks,

First check to see if logging was enabled on the server.

If so you should be able to log at the log file to find what you need.
If the logs do not go back far enough you will need to restore older logs.

Default path is C:\windows\system32\dhcp

You can confirm this in the properties window where you confirm that Auditing is enabled.
