Compacts 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. For examples of how this command can be used, see Examples.
To compact the WINS database:
CD %SYSTEMROOT%\SYSTEM32\WINS NET STOP WINS JETPACK WINS.MDB TMP.MDB NET START WINS
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:
Copies database information to a temporary database file called Tmp.mdb.
Deletes the original database file, Wins.mdb or Dhcp.mdb.
Renames the temporary database files to the original filename.
|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.|
