In System Center 2012 – Service Manager, Setup might fail when you deploy either an additional Service Manager management server or an additional Self-Service Portal in an environment where a disjoint namespace exists. This problem can occur if the Setup program is unable to resolve the principal name of the computer that is hosting the Service Manager management server. For more information, see the Microsoft TechNet article Disjoint Namespace.

We recommend that you complete the following procedures before installing either an additional Service Manager management server or an additional Self-Service Portal in an environment where a disjoint namespace exists. The first procedure shows you how to determine the principal name of your Service Manager management server. The second procedure guides you in editing the hosts file on the computer that hosts either the additional Service Manager management server or the additional Self-Service Portal.

To determine the principal name of the Service Manager management server

  1. Start a Service Manager console.

  2. In the Service Manager console, click Configuration Items.

  3. In the Configuration Items pane, expand Configuration Items, expand Computers, and then click All Windows Computers.

  4. In the All Windows Computers pane, click the computer that hosts the Service Manager management server.

  5. In the Tasks pane, under the name of the computer, click Edit.

  6. In the Computer - <computer name> window, observe that there is an Extensions tab at the top of the form. The Extensions tab appears only when you view a Service Manager management server.

  7. In the General tab in the form, in the Computer Identity area, the Principal name box shows the principal name that you will use in the following procedure.

  8. Click Close to close the form.

  9. At a command prompt, ping the Service Manager management server. You must have the IP address of the Service Manager management server for the following procedure.

To edit the hosts file

  1. On the computer that hosts either the additional Service Manager management server or the additional Self-Service Portal, start Windows Explorer, and then locate the %Systemroot%\System32\Drivers\Etc folder.

  2. Open the hosts file with Notepad by typing notepad hosts, and then press ENTER.

  3. At the end of the hosts file, add an entry starting with the IP address of the Service Manager management server followed by its principal name.

  4. Save and close the hosts file.

  5. You can now start the setup procedure for either an additional Service Manager management server or an additional Self-Service Portal.
