Microsoft Windows NT Server includes a utility, Jetpack.exe, that can be used to compact a Windows Internet Name Service (WINS) or Dynamic Host Configuration Protocol (DHCP) database. Microsoft recommends that you compact the WINS database whenever it approaches 30 MB.
NOTE: Chapter 5 page 133 of the Microsoft Windows NT Server versions 3.5 and 3.51 TCP/IP manuals states that Compact.exe can be executed to compact the WINS database. This is not correct. The correct file name is Jetpack.exe.
If the WINS/DHCP service is a resource within a Windows 2000 Cluster, refer to the following article:
(http://support.microsoft.com/kb/283251/EN-US/ )How to Use the Jetpack Utility on a Clustered WINS/DHCP Database
The correct syntax for Jetpack.exe is:
JETPACK.EXE <database name> <temp database name>
Example commands to compact the WINS database:
NET STOP WINS
JETPACK WINS.MDB TMP.MDB
NET START WINS
Example commands to compact the DHCP database:
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:
NOTE: During the compact process, Jetpack.exe creates a temporary file with the name that is specified by the temp database name parameter. 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.
