jetpack

Compacts a Windows Internet Name Service (WINS) or Dynamic Host Configuration Protocol (DHCP) database. We recommend you compact the WINS database whenever it approaches 30 MB.

Jetpack.exe compacts the database by:

  1. Copying the database information to a temporary database file.

  2. Deleting the original database file, either WINS or DHCP.

  3. Renames the temporary database files to the original filename.

Syntax

jetpack.exe <database_name> <temp_database_name>

Parameters

Parameter Description
<database_name> Specifies the name of the original database file.
<temp_database_name> Specifies the name of the temporary database file to be created by jetpack.exe.

Note: This temporary file is removed when the compact process is complete. For this command to work properly, you must make sure your temp file name is unique and that a file with that name doesn't already exist.
/? Displays help at the command prompt.

Examples

To compact the WINS database, where Tmp.mdb is a temporary database and Wins.mdb is the WINS database, type:

cd %SYSTEMROOT%\SYSTEM32\WINS
NET STOP WINS
jetpack Wins.mdb Tmp.mdb
NET start WINS

To compact the DHCP database, where Tmp.mdb is a temporary database and Dhcp.mdb is the DHCP database, type:

cd %SYSTEMROOT%\SYSTEM32\DHCP
NET STOP DHCPSERVER
jetpack Dhcp.mdb Tmp.mdb
NET start DHCPSERVER
