Syntax

Parameter Set: Set1
Set-DhcpServerDatabase [[-FileName] <String> ] [[-BackupPath] <String> ] [-AsJob] [-BackupInterval <UInt32> ] [-CimSession <CimSession[]> ] [-CleanupInterval <UInt32> ] [-ComputerName <String> ] [-PassThru] [-RestoreFromBackup <Boolean> ] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed Description

The Set-DhcpServerDatabase cmdlet modifies one or more configuration parameters of the database of the Dynamic Host Configuration Protocol (DHCP) server service.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerDatabase

Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DHCP/DhcpServerDatabase

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.


Examples

EXAMPLE 1

This example sets the file name to D:\NewDhcpPath\dhcp.mdb and the backup path to D:\NewDhcpPath\backup. This cmdlet also sets the periodicity of the database backup to 30 minutes and the periodic cleanup of the database to 120 minutes.


PS C:\> Set-DhcpServerDatabase -ComputerName dhcpserver.contoso.com -FileName D:\NewDhcpPath\dhcp.mdb -BackupPath D:\NewDhcpPath\backup -BackupInterval 30 -CleanupInterval 120
