You can use the Active Directory Sites and Services snap-in to create new site links.

Membership in the Enterprise Admins group in the forest or the Domain Admins group in the forest root domain, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at https://go.microsoft.com/fwlink/?LinkId=83477.

To create a site link
  1. Open Active Directory Sites and Services. To open Active Directory Sites and Services, click Start, click Administrative Tools, and then click Active Directory Sites and Services.

  2. In the console tree, right-click the intersite transport protocol that you want the site link to use.

    Where?

    • Active Directory Sites and Services\Sites\Inter-Site Transports\IP or SMTP

  3. Click New Site Link.

  4. In Name, type the name for the site link.

  5. In Sites not in this site link, click a site to add to the site link, and then click Add. Repeat to add more sites to the site link. To remove a site from the site link, in Sites in this link, click the site, and then click Remove.

  6. When you have added the sites that you want to be connected by this site link, click OK.

Important

Use the IP intersite transport unless your network has remote sites where network connectivity is intermittent or end-to-end IP connectivity is not available. Simple Mail Transfer Protocol (SMTP) replication has restrictions that do not apply to IP replication. For more information about using the SMTP transport, see Understanding Replication Between Sites.

Additional considerations

  • To perform this procedure, you must be a member of the Enterprise Admins group in the forest or the Domain Admins group in the forest root domain, or you must have been delegated the appropriate authority. As a security best practice, use Run as administrator to perform this procedure. Log on with your lowest-level user account and use administrative credentials when you manage Active Directory Domain Services (AD DS).
