The Netsh commands for DHCP offer a command-line tool that helps with the administration of DHCP servers and provides an equivalent alternative to console-based management. This can be useful in the following situations:

When managing DHCP servers in wide area networks (WANs), commands can be used in interactive mode at the Netsh command prompt to better manage across slow-speed network links.
When managing a large number of DHCP servers, commands can be used in batch mode at the Netsh command prompt to help script and automate recurring administrative tasks that need to be performed for all DHCP servers.

You can run these commands from the Windows Server 2003 family command prompt or from the command prompt for the Netsh DHCP context. For these commands to work at the Windows Server 2003 family command prompt, you must type netsh dhcp before typing commands and parameters as they appear in the syntax below. There might be functional differences between Netsh context commands on Windows 2000 and the Windows Server 2003 family.

dump

Dumps the configuration of the local DHCP server to the command prompt window when run within the netsh environment.

Syntax

dump

When run at the command prompt or in a batch file, output can be saved in a text file. Used without parameters, this command dumps the configuration of the local server to the command prompt window.

Syntax

netsh dhcp server [IPAddress] dump >[PathAndFileName]

Parameters

IPAddress

Specifies the IP address of the DHCP server for which the configuration is output.

PathAndFileName

Specifies both the location where the file is saved, and the name of the destination file to which to dump DHCP server configuration. If unspecified, the DHCP server configuration is dumped to the command prompt window.

Remarks

This command dumps the DHCP configuration as text output within the command prompt window. You can copy or redirect this output to a file to view it in a text editor. After file output is obtained, you can use the exec command to configure another DHCP server with the same configuration.
Before performing the dump command at the source server, reconcile all scopes and fix any reported inconsistencies.
The following command dumps the current configuration for the local DHCP server (the source) to a text file named Dhcpcfg.dmp. This file can be copied to another (destination) DHCP server and used to recreate the source configuration on it. You can recreate the configuration with the following command:
dump > dhcpcfg.dmp
Before you use the exec command to execute a dump file at the destination server, complete the following steps:

Close the DHCP console at the destination server. Do not reopen the console until after you have run the exec command.

Delete all default option definitions and any user and vendor classes at the destination server.

These examples demonstrate how to use the delete optiondef and del class Netsh commands to delete all default option definitions and any user and vendor classes. You can run these commands at the dhcp server> prompt, from within the netsh environment.
- delete optiondef 76
- del class "Default BOOTP Class"
- del class "Microsoft Windows 98 Options"
On the destination server, the exec command is used to load and execute the saved configuration:

netsh exec dhcpcfg.dmp
After you use the exec command to load the dump file, you must reconcile all scopes. Use net stop dhcpserver to stop the DHCP Server service and net start dhcpserver to restart it. Once the service is restarted, DHCP database changes take effect.

Examples

The first command, which is run within the netsh environment, dumps the configuration of the local DHCP server to the command prompt window.

The second command, which is run at the command prompt, dumps the configuration of a DHCP server with IP address 192.168.0.1 to a text file named Dhcpcfg.dmp at the location C:\Dhcp\ on the local computer.

The third command, which is run at the command prompt, dumps the configuration of a DHCP server with IP address 192.168.0.1 to a text file named Dhcpcfg.dmp on a shared network folder named \\Backup\Dhcp\.

dump

netsh dhcp server 192.168.0.1 dump > C:\Dhcp\Dhcpcfg.dmp

netsh dhcp server 192.168.0.1 dump > \\Backup\Dhcp\Dhcpcfg.dmp

export

Exports the DHCP service configuration to a file.

Syntax

export [Path]FileName {all | ScopeList}

Parameters

[Path] FileName

Required. Specifies, by name, the file where the DHCP configuration will be stored. If the path, the file name, or both contain spaces, quotation marks must be used.

{all | ScopeList}

Required. Specifies which scopes you want to export. The parameter all exports all scopes. The parameter ScopeList exports the scopes that correspond to the IP addresses you list. Each IP address in the list must be separated by spaces.

Remarks

This command works only on the local server.
While the export command runs, the DHCP service is stopped and does not respond to DHCP clients seeking new leases or lease renewals.
If the DHCP service has a large number of scopes or a large number of client address leases, this command can take a long time to run.

Examples

In the first example, this command exports the complete DHCP service configuration to the file c:\Temp\Dhcpdb.

In the second example, this command exports the DHCP configuration for scopes 10.0.0.0 and 192.168.0.0 to the file c:\Temp\Dhcpdb.

In the third example, this command exports the complete DHCP service configuration to the file c:\My Folder\Dhcp Configuration. Note that both the path and file name contain spaces, so quotation marks are used.

export c:\Temp\Dhcpdb all

export c:\Temp\Dhcpdb 10.0.0.0 192.168.0.0

export "c:\My Folder\Dhcp Configuration" all

import

Imports a DHCP service configuration from a file to the local service.

Syntax

import [Path]FileName {all | ScopeList]

Parameters

[Path] FileName

Required. Specifies, by name, the file from which the DHCP configuration will be imported. If the path, the file name, or both contain spaces, quotation marks must be used.

{all | ScopeList}

Remarks

This command works only on the local server.
While the import command runs, the DHCP service is stopped and does not respond to DHCP clients seeking new leases or lease renewals.
If the DHCP service has a large number of scopes or a large number of client address leases, this command can take a long time to run.

Examples

In the first example, this command imports the complete DHCP service configuration from the file c:\Temp\Dhcpdb.

In the second example, this command imports the DHCP configuration for scopes 10.0.0.0 and 192.168.0.0 from the file c:\Temp\Dhcpdb

In the third example, this command imports the complete DHCP service configuration from the file c:\My Folder\Dhcp Configuration. Note that both the path and file name contain spaces, so quotation marks are used.
