3.1 Exporting DHCP database and configuration of local service to a file

--------------------------------------------------------------------------------

 

When exporting all scopes:

 

To ensure that the DHCP server does not assign IP address leases to client computers after export of the DHCP database and configuration, stop the DHCP service on the source server. For more information, see Windows NT 4.0 Server or Windows 2000 Server online Help.

 

When exporting some, but not all, scopes:

 

You can export some scopes without stopping the DHCP service.  During the export procedure you can select specific scopes for export.  You can also disable the selected scopes on the local computer before export, thereby preventing the DHCP server from allocating IP addresses from these scopes to clients after export.

 

>>>To export a DHCP database from a server running Windows NT 4.0 Server or Windows 2000 Server:

 

1. In Windows Explorer, locate the folder where you installed Dhcpexim.exe. Double-click Dhcpexim.exe.

2. Click Export Configuration Of Local Service To A File, and then click OK.

3. In the DHCPexim Export To File dialog box, locate the local folder where you want to store the exported DHCP database and configuration. Click File Name, and then type a file name for your DHCP database. Click Save. 

4. In the DhcpExim Export dialog box, select the scopes you want to export.  To select multiple contiguous scopes, click the first scope, scroll to the last scope, press Shift and click the last scope.  To select multiple noncontiguous scopes, hold down Ctrl and click each scope you want to export.

5. If you did not stop the DHCP service before exporting the DHCP database and configuration, select the Disable the Selected Scopes on Local Machine Before Export checkbox to prevent the DHCP server from assigning IP address leases from the selected scopes to client computers after export.

6. Click Export.

 

 

3.2 Importing DHCP database and source configuration to the local service from a file.

--------------------------------------------------------------------------------

 

If the DHCP service is not installed on the destination server, install it before starting DHCPexim.

 

Install DHCPexim.

 

>>>To import DHCP database and configuration to a server running Windows NT Server or Windows 2000 Server:

 

1. In Windows Explorer, locate the folder where you installed Dhcpexim.exe. Double-click the file to launch DHCPexim.

2. Click Import Configuration Of Local Service To A File, and then click OK.

3. In the DHCPexim Import to File dialog box, locate the local folder where the DHCP database and configuration import file is stored, and then click the file you want to import. Click Open.

4. In the DhcpExim Import dialog box, select scopes for import. To select multiple contiguous scopes, click the first scope, scroll to the last scope, press Shift, and then click the last scope. To select multiple noncontiguous scopes, hold down Ctrl and then click each scope you want to export.

5. Click Import.

4. KNOWN ISSUES

---------------- 

 

-- The tool does not display high-bit characters correctly.

 

-- On a Windows 2000 Datacenter-based DHCP server, if the SwitchedNetworkFlag registry setting is first exported and then imported to a destination server, the DHCP console shows the imported scope as deactivated. (SwitchedNetworkFlag causes the Datacenter server to assign its own IP address as the default gateway using DHCP Option 003 - router.)  On the DHCP console Action menu, the command to activate the scope is not available. 

 

To activate the scope:

 

1. on the Action menu, click Deactivate.

   The option to activate the scope becomes available. 

2. On the Action menu, click Activate.

-- Reserved IP DNS settings are not exported correctly.

-- Use of the tool might alter permissions on the directory <systemroot>\System32\Dhcp\
