How to Recover a Done DHCP

If your DHCP files corrupt, you must rebuild the DHCP tables on the Windows server. Clients rely on DHCP to assign an IP address on the computer. If the DHCP corrupts, your clients are unable to connect to the network. You back up the original DHCP file, delete it from the system and restart the DHCP service. Restarting the service rebuilds the file, so you a "done" DHCP server is rebuilt and repaired.

Instructions

1. Click the Windows "Start" button on the DHCP server. Type "cmd," and press "Enter" to open the command line.

2. Type "net stop dhcpserver," and press "Enter." This command stops the DHCP service, so you can repair the files.

3. Type the following commands to create a backup of the DHCP files:

   md c:\oldfiles

   move % SystemRoot % \system32\DHCP\*.* C:\oldfiles

   These two commands create a backup directory and move the current DHCP files to the backup directory.

4. Delete the DHCP files. Type "del % SystemRoot % \system32\DHCP\Dhcp.mdb," and press "Enter." The DHCP logs are removed from the system.

5. Restart the DHCP service. When you restart the service, the DHCP tables are rebuilt. Type "net start dhcpserver," and press "Enter" to fix and rebuild the damaged files.
