Windows To export your DHCP db for import into SQL or some other db for analysis, use the NT4 Server Resource Kit utility dhcpcmd. The syntax is: dhcpcmd  scope_address  enumclients [-v | -h] where -v is verbose and -h generates hardware information If you need to move the dhcp server db from on server to another, see  How to Move a DHCP Database to Another Windows NT Server  . That is the Microsoft way. A very conservative approach is to recreate the scopes on a new server and let them be deactivated: Use DHCPCMD to import the IP-reservations in the scopes (if there are no reservations, you don't have to do the import of course). Then, deactivate a scope from the old server and activate the corresponding scope on the new server. This should work perfectly as the clients send broadcasts to look for a DHCP server. In the clients' event logs, you'll see NACK errors from the old server. Don't worry about those, a client always checks for the last known DHCP server...

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:  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. NOTE : During the compact process, Jetpack.exe creates a temporary file with the name that is specified by the  temp database name parameter. The tempo...
