  • Article

 

Applies To: Windows Server 2012 R2, Windows Server 2012

This topic contains troubleshooting information for issues related to the Set-DAEntryPointDC command. To confirm that the error you received is related to setting the entry point domain controller, check in the Windows Event log for the event ID 10065.

Saving server GPO settings

Error received—An error occurred while saving Remote Access settings to GPO <GPO_name>.

To troubleshoot this error, see Saving server GPO settings.

Remote Access is not configured

Error received—Remote Access is not configured on <server_name>. Specify the name of a server that belongs to a multisite deployment.

Or

Remote Access is not configured on the server <server_name>. Specify a computer with DirectAccess enabled.

Cause

Remote Access is not configured on the computer specified by the ComputerName parameter.

The Set-DaEntryPointDC cmdlet is available only on servers that are part of a configured multisite deployment.

Solution

Run the command and make sure to specify the ComputerName parameter with the name of the server that is already configured as part of the multisite deployment.

Multisite is not enabled

Error received—You must enable a multisite deployment before performing this operation. Use the Enable-DAMultiSite cmdlet to do this.

Cause

Multisite is not enabled on the server specified by the ComputerName parameter.

The Set-DaEntryPointDC cmdlet is available only on servers that are part of a configured multisite deployment.

Solution

Run the command and make sure to specify the ComputerName parameter with the name of the server that is already configured as part of the multisite deployment.

Entry point and domain controller not provided in cmdlet

The Set-DaEntryPointDC cmdlet enables you to change the domain controller that is associated with different entry points, for example, if a particular domain controller is no longer available. You can update a specific entry point to use a different domain controller, or you can update all entry points which use a specific domain controller to use a new domain controller. In the first case, you should use the EntryPointName parameter to specify which entry point should be updated. In the second case, you should use the ExistingDC parameter to specify which domain controller should be replaced. You can specify only one of these parameters.

Error received—No required parameters were specified. Provide the name of an entry point or an existing domain controller.

Or

Cmdlet Set-DaEntryPointDC is missing all required parameters.

Cause

The EntryPointName or ExistingDC parameters were not specified, or both parameters were specified, for the Set-DaEntryPointDC cmdlet.

Solution

Run the command and make sure to specify either the EntryPointName parameter or the ExistingDC parameter.

Could not locate domain controller

Error received—Unable to locate a new domain controller automatically. Retry later or verify domain controller settings.

Cause

The computer specified with the ComputerName parameter is not reachable over RPC or the domain does not contain any available writable domain controllers.

Solution

Make sure that the remote computer is accessible over RPC and that there is a writable domain controller available for the domain. If a writable domain controller is available for the domain, you can also specify its name explicitly using the NewDC parameter.

Could not connect to domain controller

  • Issue 1

    Error received—The domain controller <domain_controller> cannot be reached. Check network connectivity and server availability.

    Cause

    The domain controller cannot be reached. This occurs only when the administrator specifies a domain controller in the NewDC or ExistingDC parameters.

    Solution

    Make sure that the domain controller's name is spelled correctly. If you used a short name to specify the name, use the FQDN and try again.

  • Issue 2

    Error received—The domain controller <domain_controller> cannot be contacted.

    Cause

    There may be a network issue that means the domain controller specified in the NewDC parameter, or any other existing domain controller in the configuration cannot be reached.

    Solution

    Make sure that the domain controller's name is spelled correctly, make sure it exists, is running, is writable, and that there is a trust relationship between the domain controller and the domain.

  • Issue 3

    Error received—Domain controller <domain_controller> cannot be reached for %2!s!.

    Cause

    To maintain the configuration consistency in a multisite deployment, it is important to make sure that each GPO is managed by a single domain controller. When the domain controller that manages an entry point’s server GPO is not available, Remote Access configuration settings cannot be read or modified.

    Solution

    Follow the procedure “To change the domain controller that manages server GPOs” described in 2.4. Configure GPOs.

  • Issue 4

    Error received—The primary domain controller in domain <domain_name> cannot be reached.

    Cause

    To maintain the configuration consistency in a multisite deployment, it is important to make sure that each GPO is managed by a single domain controller. Client GPOs are managed on the primary domain controller. If the primary domain controller is not available, Remote Access configuration settings cannot be read or modified.

    Solution

    Follow the procedure “To transfer the PDC emulator role” described in 2.4. Configure GPOs.

Read-only domain controller

Error received—The domain controller <domain_controller> is read-only. Specify a domain controller that is not read-only.

Cause

The domain controller specified with the NewDC parameter is read-only.

Solution

When using the Set-DAEntryPointDC, the NewDC parameter is used to update the domain controller associated with a particular entry point, or to update all entry points associated with a domain controller. Therefore, the new domain controller must be writable. Specify a writable domain controller in the NewDC parameter and try again.

Cannot retrieve GPO

  • Issue 1

    Error received—GPO <GPO_name> on domain controller <previous_domain_controller> cannot be retrieved from domain controller <replacement_domain_controller> because they are not in the same domain.

    Cause

    The Remote Access server and the domain controller are not in the same domain; therefore, the GPO cannot be retrieved.

    Solution

    If you tried to update a specific entry point, make sure that the new domain controller is in the same domain as the entry point server. If you tried to update a specific domain controller, make sure that the new domain controller is in the same domain as the one you are trying to replace.

  • Issue 2

    Error received—GPO <GPO_name> on domain controller <previous_domain_controller> cannot be retrieved from domain controller <replacement_domain_controller>. Wait until domain replication completes and then try again.

    Cause

    When trying to update an entry point domain controller, the cmdlet tries to read the server GPO from the new domain controller; however, the GPO cannot be found on the new domain controller because it has not yet replicated.

    Solution

    The server GPO does not exist on the new domain controller. Make sure that the GPOs have replicated successfully to the new domain controller and try again.

  • Issue 3

    Error received—You do not have permissions to access GPO <GPO_name>.

    Cause

    When trying to update an entry point domain controller, the cmdlet tries to read the server GPO from the new domain controller; however, the GPO cannot be read on the new domain controller because you do not have the correct permissions.

    Solution

    The GPO exists on the domain controller, but it cannot be read. Make sure that you have the required permissions and try again.

Entry point not part of multisite deployment

Error received—Entry point <entry_point_name> is not part of the multisite deployment. Specify an alternate value.

Cause

The entry point name you specified was not found.

Solution

Make sure that the entry point name is spelled correctly and that GPOs are replicated to the required domain controllers, and then try again. To view the assigned domain controller for each entry point, use Get-DAEntryPointDC.

Remote Access server settings

  • Issue 1

    Error received—Server <server_name> in entry point <entry_point_name> cannot be accessed.

    Cause

    When trying to update an entry point domain controller, the cmdlet tries to read and write the entry point domain controller from all relevant Remote Access servers. The cmdlet was not able to read the data from one or more Remote Access servers.

    Solution

    Make sure that all relevant Remote Access servers are running and that you have local administrator permissions on all of them and then try again.

  • Issue 2

    Error received—Settings cannot be saved to the registry on server <server_name> in entry point <entry_point_name>.

    Cause

    When trying to update an entry point domain controller, the cmdlet tries to read and write the entry point domain controller from all relevant Remote Access servers. The cmdlet was not able to write the data to one or more Remote Access servers.

    Solution

    Make sure that all relevant Remote Access servers are running and that you have local administrator permissions on all of them and then try again.

  • Issue 3

    Error received—GPO updates cannot be applied on <server_name>. Changes will not take effect until the next policy refresh.

    Cause

    When using the cmdlet Set-DAEntryPointDC, the ComputerName parameter specified is a Remote Access server in an entry point other than the last one added to the Multisite deployment.

    Solution

    Any servers that were not updated can be seen using the Configuration Status in the DASHBOARD of the Remote Access Management Console. This does not cause any functional problems; however, you can run gpupdate /force on any servers that were not updated to get the configuration status updated immediately.

Problem resolving FQDN

Error received—Server <server_name> in entry point <entry_point_name> cannot be accessed.

Cause

While getting the list of DirectAccess servers to modify, the cmdlet was not able to resolve the fully qualified domain name (FQDN) of one of the servers from its computer SID.

Solution

The entry point specified in the error message is associated with a domain controller. Make sure that the domain controller is available for the entry point. If the computer to which the specified SID belongs was removed from the domain, ignore this message and then remove the server from the multisite deployment.

No entry points to update

Warning received—Domain controller settings were not modified. If you think changes are required, ensure that cmdlet parameters are configured correctly, and that GPOs are replicated to the required domain controllers.

Cause

When calling the Set-DaEntryPointDC cmdlet with the ExistingDC parameter, DirectAccess checks all the entry points and updates the entry points that are associated with the specified domain controller. However, no entry point uses the specified ExistingDC.

Solution

To see the list of entry points and their associated domain controllers, use the Get-DAEntryPointDC cmdlet. If changes should have been made, make sure that the cmdlet parameters are spelled correctly, and that the GPOs are replicated to the required domain controllers, and then try again.
