A dynamic host configuration protocol (DHCP) server has become a standard feature on modern networks—small, medium, and large—as it automates the assigning of IP addresses and network configurations to client machines. The bottom line is that DHCP servers are vital to almost every network. So what happens if the DHCP server needs to be moved, if the DHCP hardware needs to be upgraded, or if the DHCP server crashes? In most of these cases, all of the DHCP information will need to be transferred to another machine.

Depending on the complexity of the network, and the rules by which the information is transferred, this can be a burdensome task. In the past, it would have meant directly editing the registry on the target machine—and most IT professionals do not like to edit the registry directly, since it is too easy to make a mistake and disable a system.

However, Microsoft now provides a utility called DHCPexim to move the DHCP database from a Windows NT 4.0 Server or a Windows 2000 server to Windows 2000 Server, but a DHCP server must be properly configured to use DHCPexim. In this Daily Feature, I'm going to show you how to make it work. Author's note Windows 2000 Advanced Server was used for both the export and import portions of this article. These instructions should work equally well on Windows NT 4.0 Server, as specified in the README file that comes with the DHCPexim software. Installation of DHCPexim DHCPexim is one of the free tools included with the Windows 2000 Resource Kit and is available for from the Microsoft Web site. The tool downloads as a self-extracting installer called DHCPexim_setup.exe.

Once it is downloaded, you can simply double-click on the file to begin the installation. A standard installer wizard will guide you through the installation. After the initial splash screen, you will be required to agree with the license agreement in order to proceed. Next is a prompt for where to install the software. By default the Windows 2000 Resource Kit is installed in Program Files Resource Kit, and the DHCPexim installation chooses that location as well.

You can accept the default or choose another directory and press the Install Now button to proceed. Note that Microsoft recommends the path name be kept short and kept the same for all resource kit tools that are installed, in order to facilitate later updates. Installation will proceed and when it is completed a dialog box stating that installation was successful is displayed. No reboot is necessary since no system DLLs are changed or added.

The installation will have placed the following files in the directory chosen during the install: • DHCPEXIM.exe (the executable) • dhcpexim_license.txt (the end user license agreement) • DHCPEXIM_README (a description of the tool and basic directions for use) • ToolDownloadReadme.htm (a generic install/de-install guide for all the Windows 2000 Resource Kit free download tools) The generic install/de-install file, ToolDownloadReadme.htm, suggests resource kit tools may be installed using the msiexec utility by using a.msi file. The download for DHCPexim did not contain a.msi file, so I did not test this. The generic install/de-install file also mentions the tools are only for installation under Windows 2000, although the Microsoft Web site and the included README file suggest the tool can be installed on Windows NT 4.0 Server with Service Pack 3 or higher. Using DHCPexim To run DHCPexim, find the icon for the executable in the directory chosen during the installation and double-click on it. When it opens, the dialog box shown in Figure A will be displayed.

Figure A Since the originating DHCP server must be exported before another can be imported, choose the Export Configuration Of The Local Service To A File radio button. This option is to read the content of all or part of the DHCP database and write it to a file. A standard file save box will be presented. Choose a directory and enter a file name (e.g., 'dhcp_export') and then choose Save (it is possible to save the file to a share on the new DHCP server, and that's one of the easiest ways to transfer the file). Once the file is chosen, a dialog box is present with all the scopes available on the DHCP server being exported.

Choose the scopes that are to be exported using standard Windows selection techniques, such as [Shift]-click and/or [Ctrl]-click for multiple selections. Note the Disable The Selected Scopes On Local Machine Before Export check box. This option should be selected to avoid the current DHCP server assigning network information during the export. If this option is not chosen, the Windows DHCP Manager can be used to disable the desired scopes, or the DHCP service can be stopped. Once the scopes are selected, click Export.

When the export is completed, a dialog box will be displayed saying, 'The operation completed successfully.' The file created is not readable, but it is ready for import to another DHCP server via the utility. Once the export is completed, be sure to go back to the DHCP Manager and re-activate any scopes that the DHCP server is going to manage, or restart the DHCP service if it was stopped for the export. To import the file into another DHCP server, the DHCPexim utility must be installed on that (Windows 2000) server. Follow the same installation instructions presented above.

Once DHCPexim has been installed, find the directory chosen during the installation and launch the DHCPexim executable. Since this is the destination server, choose the second radio button (in Figure A), Import Configuration To The Local Service From A File. A standard file selection dialog box will be opened. Find the file previously exported, in this case 'dhcp_export,' and choose Open. The DHCPexim utility will verify the format of the file, and if the file is valid, a dialog box with several import options will be presented. Using standard Windows selection techniques, choose all or some of the available scopes and click Import.

If the import is successful, a dialog box will be displayed with the message: 'The operation completed successfully.' Make sure the DHCP service is running and all the imported scopes have been activated. At this point, the transfer is complete. Uninstalling DHCPexim If DHCPexim is no longer needed, or does not perform as expected, it can be uninstalled using the standard Add/Remove Program Control Panel. Under Windows 2000, it is listed as 'Microsoft Tool Web Package:dhcpexim.exe.' Summing up DHCPexim DHCPexim is a free utility, and as such, it is a little rough around the edges. Some of the dialog boxes could be a little more descriptive, and it could use a little aesthetic work, but it does perform its advertised function well.

Not all networks are complex enough to have more than one DHCP scope, or more than one DHCP server, but this utility can still be useful in simply making a backup of the DHCP configuration and having it available in case there is ever a server failure.

A few months ago, I wrote a post on. As Windows Server 2008 R2 has since released, I wanted to update the information on this subject. The process has not changed in any way from my original post. I am publishing this to confirm the original steps will work whether the target server is running Windows Server 2008 or Windows Server 2008 R2. These steps describe how to move a Dynamic Host Configuration Protocol (DHCP) database from a computer that is running Microsoft Windows NT Server 4.0 or Microsoft Windows 2000 to a computer that is running Windows Server 2008 or Windows Server 2008 R2. Note These steps should not be used to migrate to or from a clustered DHCP server.

There is no direct migration path from a Windows 2000 cluster to Windows Server 2008 or Windows Server 2008 R2. A Windows 2000 cluster must be upgraded to Windows Server 2003 before DHCP can be migrated to Windows Server 2008 or Windows Server 2008 R2. For more information on migrating DHCP from a cluster on Windows Server 2003 or Windows Server 2008 to Windows Server 2008 R2, please see the following TechNet article. Note You can use the Microsoft Windows backup utility (ntbackup.exe) to back up and restore the DHCP database on a single server. Do not use the backup utility to migrate or to move a DHCP database from one DHCP server to another. 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: a. Log on to the source DHCP server by using an account that is a member of the local Administrators group. Click Start, click Run, type cmd in the Open box, and then click OK.

At the command prompt, type net stop dhcpserver, and then press ENTER. You receive a “The Microsoft DHCP Server service is stopping. The Microsoft DHCP Server service was stopped successfully” message. Type exit, and then press ENTER. Compact the DHCP database by using the JetPack utility: a. Click Start, click Run, type cmd in the Open box, and then click OK.

At the command prompt, type cd%systemroot%system32dhcp, and then press ENTER. Type jetpack dhcp.mdb temp. Pro Evolution Soccer 3 Pc Ita Download Games. mdb, and then press ENTER.

After the database is compacted successfully, type exit, and then press ENTER. 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: To export the database: a. Install the Dhcpexim.exe utility, and then start the Dhcpexim.exe utility. At the Welcome to DHCP Export Import tool screen, click Export configuration of the local service to a file, and then click Ok. In the File name box, type the file name for the exported file, and then click Save. For example, type dhcpdatabase.txt. 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.

Disable the DHCP Server service on the server. Disabling the DHCP Server service prevents the service from starting after the database has been transferred.

To disable the DHCP Server service: a. Click Start, point to Settings, click Control Panel, and then double-click Services. In the Service list, click Microsoft DHCP Server, click Startup, click Disabled, and then click OK. If the service is started, click Stop, and then click Yes to confirm the stopping of the service. 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 2008 or Windows Server 2008 R2. Netsh commands for DHCP are not available in Windows NT 4.0.

Note If only the configuration (not the database) is required, use the following command (instead of Dhcpexim.exe) on the Windows 2000-based server that you want to export from. (Do not use Dhcpexim.exe.) netsh dhcp dump >C:dhcp.txt where C:dhcp.txt is the name and path of the export file that you want to use. Note The export option does not exist in the netsh command on Windows 2000 Server. The netsh dhcp server dump and netsh dhcp server import commands are not compatible. If you try to import the data that is created by netsh dhcp server dump >C:dhcp.txt by using netsh DHCP server import >C:dhcp.txt, you receive the following error message on the Windows Server 2008 or Windows Server 2008 R2-based computer: The request is not supported.

You can migrate the exported configuration file to the new Windows Server 2008/R2 server by using the following command: netsh exec c:dhcp.txt Install the DHCP server service on the server that is running Windows Server 2008 or Windows Server 2008 R2 To install the DHCP Server service on an existing Windows Server 2008/R2-based computer: 1. Click Start, point to All Programs, point to Administrative Tools, and then click Server Manager. In the console tree of Server Manager, right-click Roles, and then click Add Roles. In the Add Roles Wizard, click Next. On the Select Server Roles page, click to select the DHCP Server check box, and then click Next.

Review the information on the Introduction to DHCP Server page, and then click Next. Follow the instructions in the Add Roles Wizard to complete the installation. Import the DHCP database Note You may receive an “access denied” message during this procedure if you are not a member of the Backup Operators group. If you receive an “Unable to determine the DHCP server version for server” error message, make sure that the DHCP Server service is running on the server and that the user logged on is a member of the local Administrators group. Important Do not use Dhcpexim.exe to import a DHCP database in Windows Server 2008 or Windows Server 2008 R2.

Additionally, if the target Windows Server 2008 / Windows Server 2008 R2 server is a member server, and if you plan to promote it to a domain controller, we suggested that you perform the DHCP database migration before promoting it to a domain controller. Although you can migrate the DHCP database to a Windows 2008/R2 domain controller, the migration to a member server will be easier because of the existence of the local administrator account. Log on as a user who is an explicit member of the local Administrators group. A user account in a group that is a member of the local Administrators group will not work. If a local Administrators account does not exist for the domain controller, restart the computer in Directory Services Restore Mode, and use the administrator account to import the database as described later in this section.

Copy the exported DHCP database file to the local hard disk of the Windows Server 2008/R2-based computer. Verify that the DHCP service is started on the Windows Server 2008/R2-based computer.

Spice Mi 349 Flash Tool Free Download. Click Start, click Run, type cmd in the Open box, and then click OK. 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 2008/R2 member server of the domain, you may receive the following error message: Error initializing and reading the service configuration – Access Denied Note You must have local administrator permissions to import the data. To resolve this issue, add the Windows Server 2008/R2 DHCP server computer to the DHCP Admins group at the Enterprise level. If the “access is denied” error message occurs after you add the Windows Server 2008/R2 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 Administrators 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. After you receive the message that the command completed successfully, quit the command prompt.

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 by using an account that is a member of the Administrators group. In an Active Directory domain, you must be logged on to the server by using an account that is a member of the Enterprise Administrators group.

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. Right-click the server object, and then click Authorize. After several moments, right-click the server again, and then click Refresh. A green arrow indicates that the DHCP server is authorized.
