How to Use Jetpack.exe to Compact a WINS or DHCP Database

SUMMARY
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:
283251 (http://support.microsoft.com/kb/283251/EN-US/) How to Use the Jetpack Utility on a Clustered WINS/DHCP Database
MORE INFORMATION
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 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.

How to use the Jetpack utility on a clustered WINS/DHCP database

SUMMARY
This article discusses how to use the Jetpack utility on a Windows Internet Name Service (WINS) and Dynamic Host Configuration Protocol (DHCP) database with the Windows Clustering feature.

MORE INFORMATION
In Microsoft Windows Server 2003 and in Microsoft Windows 2000, the Windows Clustering feature can make the WINS and the DHCP service more readily available. These services are installed and configured on the Windows Clustering feature as cluster resources.

For more information about how to configure these resources, click the following article number to view the article in the Microsoft Knowledge Base:
226796 (http://support.microsoft.com/kb/226796/) Using WINS and DHCP with the Windows 2000 Cluster service

Note The use of the the Jetpack utility on either a WINS or DHCP database on a server cluster requires special procedures that may deviate slightly from those documented in the following article.

For more information, click the following article number to view the article in the Microsoft Knowledge Base:
145881 (http://support.microsoft.com/kb/145881/) How to use Jetpack.exe to compact a WINS or DHCP database
To use the Jetpack utility on a WINS or DHCP database which runs on a Windows 2000-based server cluster: 1. Start Cluster Administrator. Ensure that the group that contains the WINS or DHCP service resource is currently owned by the cluster node you are logged into and in which you intend to run the Jetpack utility.

2. In Cluster Administrator, right-click WINS/DHCP service resource, and then click Take Offline. (For DHCP service, substitute DHCP for WINS.) If the resource is not taken offline, the following error message may be displayed:
Jetpack failed with error = -1032

3. When the WINS or DHCP resource is offline, at a command prompt, change the working folder to the System32\Wins folder (or Dhcp folder) on the shared drive.

4. At a command prompt, type: jetpack wins.mdb temp.mdb ( or "dhcp.mdb" for the DHCP service). If a Jetpack utility command is successful (for the WINS database in this example), you may receive the following message:
Compacted database wins.mdb in 1.469 seconds.

moving temp.mdb => wins.mdb
Jetpack completed successfully.

5. After the Jetpack utility has run, right-click WINS/DHCP service resource in the Cluster Administrator, and then click Bring Online.
