SUMMARY
This step-by-step article describes how to move a Dynamic Host Configuration Protocol (DHCP) database from a computer that is running Microsoft Windows NT Server 4.0, Microsoft Windows 2000, or Microsoft Windows Server 2003 to a computer that is running Windows Server 2003.
back to the top
Export the DHCP database from a server that is running Windows NT Server 4.0 or Windows 2000
1.. Stop the DHCP Server service on the server:
1.. Click Start, click Run, type cmd in the Open box, and then click OK.
2.. At the command prompt, type net stop "microsoft dhcp server", and then press ENTER. You receive a "The Microsoft DHCP Server service is stopping. The Microsoft DHCP Server service was stopped successfully" message.
3.. Type exit, and then press ENTER.
2.. Compact the DHCP database by using the JetPack utility:
1.. Click Start, click Run, type cmd in the Open box, and then click OK.
2.. At the command prompt, type cd %systemroot%\system32\dhcp, and then press ENTER.
3.. Type jetpack dhcp.mdb temp.mdb, and then press ENTER.
4.. After the database is compacted successfully, type exit, and then press ENTER.
3.. Export the DHCP database by using the DHCP Export Import utility (Dhcpexim.exe). You can obtain this utility from the Windows 2000 Resource Kit Supplement 1. You can also visit the following Microsoft Web site to obtain Dhcpexim.exe:
http://www.microsoft.com/windows2000/techinfo/reskit/tools/new/dhcpexim-o..asp
To export the database:
1.. Install the Dhcpexim.exe utility, and then start the Dhcpexim.exe utility.
2.. At the Welcome to DHCP Export Import tool screen, click Export configuration of the local service to a file, and then click Ok.
3.. In the File name box, type the file name for the exported file, and then click Save. For example, type dhcpdatabase.txt.
4.. Click the scope or scopes that you want to export, click to select the Disable the selected scopes on local machine before export check box, and then click Export.
5.. Click OK.
3.. Disable the DHCP Server service on the server:
1.. Click Start, point to Settings, click Control Panel, and then double-click Services.
2.. In the Service list, click Microsoft DHCP Server, click Startup, click Disabled, and then click OK.
3.. If the service is started, click Stop, and then click Yes to confirm the stopping of the service.
4.. Click Close to close the Services dialog box.
Important Dhcpexim.exe is required to move the database successfully from a server that is running Windows 2000 to a server that is running Windows Server 2003. If only the configuration (not the database) is required, use the following command on the Windows 2000-based server that you want to export from
netsh dhcp server export C:\dhcp.txt all
where C:\dhcp.txt is the name and path of the export file that you want to use.

Export the DHCP database from a server that is running Microsoft Windows Server 2003
To move a DHCP database and configuration from a server that is running Windows Server 2003 to another server that is running Windows Server 2003:
1.. Click Start, click Run, type cmd in the Open box, and then click OK.
2.. Type netsh dhcp server export C:\dhcp.txt all, and then press ENTER.
3.. Copy the file to the new server.
4.. Type netsh dhcp server import C:\dhcp.txt all, and then press ENTER.
back to the top
Install the DHCP server service on the server that is running Windows Server 2003
To install the DHCP Server service on an existing Windows Server 2003-based computer:
1.. Click Start, click Control Panel, and then double-click Add or Remove Programs.
2.. Click Add/Remove Windows Components.
3.. In the Windows Component Wizard, click Networking Services in the Components box, and then click Details.
4.. Click to select the Dynamic Host Configuration Protocol (DHCP) check box if it is not already selected, and then click OK.
5.. In the Windows Components Wizard, click Next to install the selected components. Insert the Windows Server 2003 CD-ROM into your computer CD-ROM or DVD-ROM drive if you are prompted to do so. Setup copies the DHCP server and tool files to your computer.
6.. When Setup is complete, click Finish.
back to the top
Import the DHCP database
1.. Copy the exported DHCP database file to the local hard disk of the Windows Server 2003-based computer.
2.. Verify that the DHCP service is started on the Windows Server 2003-based computer.
3.. Click Start, click Run, type cmd in the Open box, and then click OK.
4.. At the command prompt, type netsh dhcp server import c:\dhcpdatabase.txt all, and then press ENTER, where c:\dhcpdatabase.txt is the full path and file name of the database file that you copied to the server.
Note When you try to export a DHCP database from a Windows 2000 domain controller to a Windows Server 2003 member server of the domain, you may receive the following error message:
Error initializing and reading the service configuration - Access Denied
To resolve this issue, add the Windows Server 2003 DHCP server computer to the DHCP Admins group at the Enterprise level.
5.. If the "access is denied" error message occurs after you add the Windows Server 2003 DCHP server computer to the DHCP Admins group at the Enterprise level that is mentioned in step 4, verify that the user account that is currently used to import belongs to the local administrator's group. If the account does not belong to this group, add the account to that group, or log on as a local administrator to complete the import.
6.. After you receive the message that the command completed successfully, quit the command prompt.
back to the top
Authorize the DHCP server
1.. Click Start, point to All Programs, point to Administrative Tools, and then click DHCP.
Note You must be logged on to the server with an account that is a member of the Enterprise Administrators group.
2.. In the console tree of the DHCP snap-in, expand the new DHCP server. If there is a red arrow in the lower-right corner of the server object, the server has not yet been authorized.
3.. Right-click the server object, and then click Authorize.
4.. After several moments, right-click the server again, and then click Refresh. A green arrow indicates that the DHCP server is authorized.

SUMMARY
This article describes how to move the zone files from one DNS server that is running Windows 2000 to another DNS server that is running Windows 2000.

Move Zone Files
To move zone files from one server to another, follow these steps:
Note To use the following method, the Windows 2000 DNS Server service must be installed on a new Windows 2000-based server. The DNS Server service should not be configured yet.
1.
On the DNS server that is currently hosting the DNS zone(s), change any Active Directory-integrated zones to standard primary. This action creates the zone files that are needed for the destination DNS server.
2.
Stop the DNS Server service on both DNS servers.
3.
Manually copy the entire contents (subfolders included) of the %SystemRoot%\System32\DNS folder from the source server to the destination server.
4.
On the current DNS server, start Registry Editor (Regedit.exe).
5.
Locate and click the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DNS\Zones
6.
Export the Zones entry to a registry file.
7.
Locate and click the following registry subkey: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\DNS Server\Zones
8.
Export the Zones entry to a registry file.
9.
On the destination DNS server, double-click each registry file to import the Zonessubkeys into the registry.
10.
Bring the current DNS server down and transfer its IP address to the destination DNS server.
11.
On the destination DNS server, start the DNS Server service. To initiate the registration of the server's A and PTR resource records, run the following command at a command prompt:
ipconfig /registerdns
12.
If this server is also a domain controller, stop and restart the Net Logon service to register the Service (SRV) records, or run the following command at a command prompt:
netdiag /fix
13.
The standard zones that were previously Active Directory-integrated can be converted back to Active Directory-integrated on the replacement DNS server if it is a domain controller.
14.
Verify that the SOA resource records on each zone contains the correct name for the primary server and that the NS resource records for the zone(s) are correct.
Note The steps outlined in this article do not migrate the following DNS server settings:
•
Interfaces
•
Forwarders
•
Advanced
•
Root Hints
•
Logging
•
Security
•
Any specific registry setting made under any keys other than the key that is specified in step 4
