DHCP SERVER Jetpack.exe

The correct syntax for Jetpack.exe is: 

JETPACK.EXE <database name> <temp database name>

Example commands to compact the WINS database: 

CD %SYSTEMROOT%\SYSTEM32\WINS
NET STOP WINS
JETPACK WINS.MDB TMP.MDB
NET START WINS

Example commands to compact the DHCP database: 

CD %SYSTEMROOT%\SYSTEM32\DHCP
NET STOP DHCPSERVER
JETPACK DHCP.MDB TMP.MDB
NET START DHCPSERVER

In the examples above, Tmp.mdb is a temporary database that is used by Jetpack.exe. Wins.mdb is the WINS database. Dhcp.mdb is the DHCP database. 

Jetpack.exe compacts the WINS or DHCP database by doing the following: 

1. Copies database information to a temporary database file called Tmp.mdb.
2. Deletes the original database file, Wins.mdb or Dhcp.mdb.
3. Renames the temporary database files to the original filename.

NOTE: During the compact process, Jetpack.exe creates a temporary file with the name that is specified by the temp database nameparameter. The temporary file is removed when the compact process is complete. Make sure you do not have a file already existing in WINS or DHCP folder with the same name as the one specified in the temp database name parameter.
