Using Sites in Windows 2000 - Page 3
So far, I've shown you how to create sites; but a critical piece of the puzzle is still missing. Unless you link the sites, replication will never occur between them. Remember that as far as Windows 2000 is concerned, each site is a separate entity unless you tell it otherwise. The task of linking sites is accomplished by a mechanism known as a site link.. A site link is bound to a protocol that both sites joined by the link can use to communicate. The site link itself also contains the replication schedule and various security mechanisms.
When you create your first site, Windows 2000 automatically creates one site link. This is the DEFAULTSITELINK that you saw earlier when you created the site. If you had selected this option when creating a site, this site link would be used to join the new site to any existing sites that were also set to use the link.
You can access the DEFAULTSITELINK by going into the Active Directory Sites and Services snap-in and navigating to Active Directory Sites and Services|Sites|Inter-Site Transports|IP. When you select the IP folder, the DEFAULTSITELINK will appear in the column on the right. Right-click on the DEFAULTSITELINK and select Properties from the context menu. When you do, you'll see the DEFAULTSITELINK's Properties sheet. The General tab displays which sites are linked by the site link. The tab also displays the link's cost and replication schedule. You can use the Change Schedule button to replicate the connected sites more or less often. The default replication schedule is set to replicate the connected sites every 180 minutes.
By looking through the various options found on the properties sheet, you can easily establish basic inter-site replication. However, this is just the tip of the proverbial replication iceberg. I cover site links and replication in more detail in part 2 of this series ( Inter-site Replication ). //
