Syntax

Parameter Set: Remove2
Remove-DhcpServerInDC [[-DnsName] <String> ] [[-IPAddress] <IPAddress> ] [-AsJob] [-CimSession <CimSession[]> ] [-PassThru] [-ThrottleLimit <Int32> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Detailed Description

The Remove-DhcpServerInDC cmdlet deletes the specified Dynamic Host Configuration Protocol (DHCP) server service from the list of authorized DHCP server services in Active Directory (AD).

When neither the DnsName nor the IPAddress parameter is specified, then the local DHCP server service will be removed from the list of authorized DHCP server services in AD.

If only the DnsName parameter is specified, then the DHCP server service running on the computer with the specified DNS name will be removed from the list of authorized DHCP server services in AD.

If the DnsName and the IPAddress parameters are specified, then the DHCP server service running on the computer with specified values will be removed from the list of authorized DHCP server services in AD.

If only the IPAddress parameter is specified, then an error is returned.

In addition to removing the computer running the DHCP server service in DC, this cmdlet also triggers the DHCP server service to perform an authorization check.

The trigger for authorization check will be done even if the removal of computer running the DHCP server service fails with an object already exists error.

The following warning will be displayed if the computer running the DHCP server service does not exist in AD and the trigger for the server authorization check succeeded:
- The DHCP server is already de-authorized in Active Directory. The authorization check on the DHCP server has been initiated.

The following warning will be displayed if the computer running the DHCP server service does not exist in AD, but the trigger for the server authorization check failed:
- The DHCP server is already de-authorized in Active Directory. Failed to initiate the authorization check on the DHCP server. Error code: %d

The following warning will be displayed if the deletion of the computer running the DHCP server service in AD succeeded, but the trigger for the server authorization check failed:
- The DHCP server has been successfully de-authorized in Active Directory. Failed to initiate the authorization check on the DHCP server. Error code: %d

If the deletion of computer running the DHCP server service to AD fails with an error other than object_does not already_exists_error, then an error is returned and authorization check on the server is not triggered.

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/DhcpServerInDC

  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.

Outputs

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

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

  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 deletes the object in the AD domain for the DHCP server service running on the computer with the DNS name dhcpserver.contoso.com and the IP address 10.10.10.2, thereby de-authorizing the DHCP server service for clients on the network.

PS C:\> Remove-DhcpServerInDC -DnsName dhcpserver.contoso.com -IPAddress 10.10.10.2

EXAMPLE 2

This example deletes an object in the AD domain for the DHCP server service running on the computer with the DNS name dhcpserver.contoso.com, thereby de-authorizing the DHCP server service for the clients on the network. The IP address for computer running the DHCP server service object in AD will be obtained by looking up dhcpserver.contoso.com in DNS.

PS C:\> Remove-DhcpServerInDC -DnsName dhcpserver.contoso.com

EXAMPLE 3

This example deletes an object in the AD domain for the DHCP server service running on the local computer.

PS C:\> Remove-DhcpServerInDC
