When a you try to run Jetpack.exe on the Jet database of a Dynamic Host Configuration Protocol (DHCP) server on a computer running Windows NT Server version 4.0, you may receive the following error message:
When compacting the database using Jetpack, a Jet database duplicate key error -1605 may occur. This error occurs when addresses are marked bad and a unique value is not used for the media access control hardware address associated with the bad IP addresses.

This problem may go away temporarily if you delete the database and reconcile. This problem may also result in the DHCP server ceasing to respond (hanging).
