Using Setup to Run Forest Preparation

If Active Directory replication of the schema preparation changes has not completed, an error occurs. Wait for replication to complete or force replication before running the Prep Forest wizard.

You might want to decide where to store global settings before starting this procedure. If connectivity to the root domain is unreliable, select the Configuration partition. For details about selecting the location, see Deciding Where to Store Global Settings.

The Prep Forest wizard requires that you specify the Session Initiation Protocol (SIP) domain to be used for default routing. The default SIP domain is used to construct the server SIP Uniform Resource Identifier (URI), which in the simplest form is <ServerFQDN>@<DefaultSIPDomainFQDN>. The wizard identifies a default SIP domain as follows:

  • In new deployments, the root domain is always proposed as the default SIP domain.
  • For existing deployments, if no default SIP domain exists, all existing SIP domains appear as possible options, and the wizard selects one domain randomly as the default routing domain.
  • If a default SIP domain already exists, the wizard populates the list with all existing SIP domains and selects the default SIP domain.

You must be a member of the EnterpriseAdmins group for the forest root domain to perform this procedure.

If you are currently using Office Communications Server 2007 and the forest preparation for Office Communications Server 2007 R2 fails, the rollback might remove access control lists (ACLs) that are required for Office Communications Server 2007 to work properly. If this problem occurs, run Office Communications Server 2007 forest preparation again to restore the missing ACLs, and then run forest preparation for Office Communications Server 2007 R2.

  1. From the Office Communications Server installation folder or CD, run SetupEE.exe (for Enterprise Edition server consolidated configuration) or SetupSE.exe (for Standard Edition server) to start the deployment tool.

  2. Click Prepare Environment.

  3. Click Prepare Active Directory.

  4. At Prep Forest, click Run.

  5. On the Welcome to the Forest Preparation Wizard page, click Next.

  6. On the Select Location to Store Global Settings page, do one of the following:

    • To store settings in the configuration partition, click Configuration partition. This is the recommended location.
    • To store settings in the System container of the root domain, click System container in the root domain. Select this location only if all sites have very good network connectivity to root domain controllers.
  7. On the Location of Universal Groups page, under Domain, select the domain where you want to create the groups used by Office Communications Server, and then click Next.

  8. On the SIP domain used for default routing page, select the SIP domain that you want to use for default routing.

    Dd425108.note(en-us,office.13).gifNote:
    Keep the suggested default SIP domain, use the list to select another existing domain as the default SIP domain, or type in a new domain FQDN for the default SIP domain.
  9. On the Ready to Prepare Forest page, review your current settings before clicking Next.

  10. On the Forest Preparation Wizard has Completed page, click View Log.

  11. Under the Action column, expand Forest Prep, look for <Success> Execution Result at the end of each task to verify that forest preparation completed successfully, close the log, and then click Finish.

  12. Wait for Active Directory replication to complete, or force replication to all domain controllers listed in the Active Directory Sites and Services snap-in for the forest root domain controller, before running domain preparation. Force replication between the domain controllers in all Active Directory sites to cause replication within the sites to occur within minutes.
