You can change the port numbers used by Configuration Manager 2007 clients to communicate with site systems that use HTTP and HTTPS for communication. You can specify both a default port and an alternative port to use if communication using the default port fails. You can specify settings for both HTTP (mixed mode) and HTTPS (native mode) data communication.

The default values for these ports are 80 for HTTP traffic and 443 for HTTPS traffic. Change them only if you do not want to use these default values.

Do not change the port numbers in Configuration Manager 2007 without understanding the consequences. For example, changing the port numbers for the client request services might result in clients being unable to connect to Configuration Manager 2007 site systems, resulting in them becoming unmanaged.

Changing the default request port numbers requires that the site is configured with the new request port numbers and that clients are configured to use the new request port numbers. When you change the request ports on a primary site, any attached secondary sites automatically inherit the same port configuration. Use the procedure in this topic to configure the request ports on the primary site.

When the Configuration Manager site is published to Active Directory Domain Services, new and existing clients that can access this information will automatically be configured with their site port settings and you do not need to take further action. Clients that cannot access this information published to Active Directory Domain Services include workgroup clients, clients from another Active Directory forest, clients that are configured for Internet-only, and clients that are currently on the Internet. If you change the default port numbers after these clients have been installed, reinstall them and install any new clients by using one of the following methods:

To reconfigure the port numbers for existing clients, you can also use the script PORTSWITCH.VBS that is provided with the installation media in the \Tools\PortConfiguration folder.

For existing and new clients that are currently on the Internet, you must configure the non-default port numbers by using the CCMSetup.exe client.msi properties of CCMHTTPPORT and CCMHTTPSPORT.

After changing the request ports on the site, new clients that are installed by using the site-wide Client Push installation method will be automatically configured with the current port numbers for the site.

To configure the request ports on the site

  1. In the Configuration Manager console, navigate to System Center Configuration Manager / Site Database / Site Management.

  2. Right-click <site code> – <site name>, and then click Properties.

  3. On the Ports tab in the site properties dialog box, view the Active Ports list.

  4. Select any of the Client Request items and click the Properties icon to display the Port Detail dialog box.

  5. In the Port Detail dialog box, specify the port number and description for the item, and then click OK.

  6. When you have finished configuring client request ports, click OK to close the site properties dialog box.
