How can I compress my DHCP database?

A. NT Server ships with a utility called JETPACK.EXE which can be used to compact DHCP and WINS databases. To compact your DHCP database perform the following:
Start a command prompt (cmd.exe)
Enter the following commands
cd %SystemRoot%SYSTEM32DHCP
e.g. cd d:winntsystem32dhcp
net stop DHCPSERVER
jetpack DHCP.MDB TMP.MDB
net start DHCPSERVER
Note: While you stop the DHCP service, clients using DHCP to receive a TCP/IP address will not be able to start this protocol and may hang.
Jetpack actually compacts DHCP.MDB into TMP.MDB, then deletes DHCP.MDB and copies TMP.MDB to DHCP.MDB! Simple :-)
