| Migrate DHCP to another server |
| Before you migrate DHCP on your production server, you should create a backup and perform test |
| migrations. When you do the migration, follow these steps exactly. |
| Disable the DHCP service on server1 by using the Services console. Make sure you set Disabled |
| under Startup Type for the services. |
| Stop your service from the command prompt using net stop dhcpserver. |
| Open the Regedt32.exe and go to |
| HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DhcpServer\Configuration |
| Select the Configuration Key and click Save Key on the Registry menu. Save the key in the |
| Install the DHCP service on server2, through the Add/Remove Programs wizard. |
| Stop the DHCP service on computer1 using net stop dhcpserver in the command prompt. |
| Copy the Config.key file from server1 to server2. |
| On server2, use the Regedt32.exe and go to |
| HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DhcpServer\Configuration |
| Select the Configuration key and click Restore from the Registry menu. Select the Config.key file |
| Delete the %systemroot%\System32\Dhcp folder, including subfolders on server2. |
| Copy the %systemroot%\System32\Dhcp\Dhcp.mdb from server1 to server2. |
| Use net start dhcpserver to start the DHCP service on server2. |
| Open the DHCP Server console from the Administrative Tools on server2. |
| Right-click server2 and select Reconcile All Scopes. Click Verify. |
| If this compute is part of the Active Directory domain, authorize it. |
| This isn't the only way to migrate DHCP. Supplement 1 for the Windows 2000 Resource Kit |
| includes DHCPExIm.exe, which can move the DHCP scopes from one server to another. |
| Also note that not all DHCP settings are migrated. After you migrate the database, reconfigure |
| your DHCP settings, like Logging, Backup interval, and so on. |
| Reminder: Once again, editing the registry can be risky, so be sure you have a verified backup |
| before making any changes. |
