Configuration Manager Client Mixed Mode Issues

Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

This section provides troubleshooting information to help you resolve issues that are specific to Configuration Manager 2007 clients when they are operating in a mixed-mode site. For issues that affect both mixed-mode and native-mode clients, see Configuration Manager Client General Issues.

Most client troubleshooting issues that are specific to mixed-mode operations relate to the approval process. For more information about client approval, see About Client Approval in Configuration Manager.

If Configuration Manager 2007 clients do not automatically approve, even though you are using the default site setting of Automatically approve computers in trusted domains (recommended), the following situations might be the cause:

  • Client computers do not belong to the same domain as the site server's domain, and the site's default management point is not configured with a fully qualified domain name (FQDN).

  • Clients belong to a separate Active Directory forest or are workgroup computers.

  • You are using a network load balancing (NLB) management point.

  • You have changed the site approval setting after clients have successfully been assigned to the site.

For more information about client approval, see About Client Approval in Configuration Manager.

Solution

Refer to the following table to troubleshoot each situation listed above.

 

Situation Solution

Client computers do not belong to the same domain as the site server's domain, and the site's default management point is not configured with a fully qualified domain name (FQDN).

Configure the site system that holds the default management point role with an FQDN:

Clients belong to a separate Active Directory forest or are workgroup computers.

This is by design, and you must manually approve these clients because they cannot be automatically verified using Windows integrated authentication.

See the procedure "To approve clients manually" in the following topic:

You are using an NLB management point.

This scenario requires the following additional configuration:

  1. Confirm that the NLB management point is configured to use an FQDN. For more information, see How to Configure the Intranet FQDN of an NLB Management Point.

  2. Configure a Service Principal Name (SPN) in Active Directory Domain Services for the FQDN NLB management point cluster. For more information, see How to Configure an SPN for NLB Management Point Site Systems.

You have changed the site approval setting after clients have successfully been assigned to the site.

This is by design, because the client approval state is set when the client is assigned to a site.

To approve clients that have successfully been assigned to the site but are unapproved, perform either of the following actions:

If a client computer in mixed mode has an Internet-based management point specified, the client repair function fails. This configuration is possible only in the following two scenarios:

  • The Configuration Manager 2007 site was in native mode, and clients were configured to use an Internet-based management point. If the site is reverted to mixed mode, clients automatically retain their Internet-based management point configuration.

  • Native-mode clients configured to use an Internet-based management point are reassigned to a mixed-mode site, and they automatically retain their Internet-based management point configuration.

Solution

Reinstall the Configuration Manager 2007 client. If reinstalling the client is not an acceptable solution, you can clear the Internet-based management point (FQDN) entry by removing the data in the registry key Internet MP Hostname, which is located under HKLM\Software\Microsoft\SMS\Client\Internet Facing.

The Approve option remains available for an approved client, and selecting it does not result in updated log files.

For more information about client approval, see About Client Approval in Configuration Manager.

Solution

Do not select the Approve option for a client that displays as Approved. Selecting this option has no effect when the client is already approved. To confirm that a client is approved, reference the client state in the Configuration Manager console. For more information, see About Client States in Configuration Manager.
