SYMPTOMS
When Jetpack.exe (Jetpack) is used to compact Wins.mdb or Dhcp.mdb, it may complete without an error and still be using the original Wins.mdb or Dhcp.mdb. This happens when Jetpack is run and a temporary file is specified on a partition other than the one where the original .mdb file is located. Jetpack will display a message that it is moving the temp file to the original location and then respond that Jetpack completed successfully.



CAUSE
After Jetpack writes the new .mdb files to the location specified on the command line, it removes the original and moves the Temp.mdb while renaming it Wins.mdb or Dhcp.mdb. Jetpack can only move files that are located on the same partition. When Jetpack moves a file to a different partition, it actually copies the file then renames it if necessary. When Jetpack can not move the file successfully it does not report an error and gives a message that Jetpack was successful.



RESOLUTION
It may be necessary to run Jetpack with the temp file located on a different partition than the original WINS or DHCP database due to disk resources. If this is necessary, copy the temp file back to the Wins or Dhcp directory and rename it to Wins.mdb or Dhcp.mdb prior to restarting the WINS or DHCP service.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in Windows NT version 4.0.
