As discussed in Lesson 1, when more than two sites are linked for MCTS certification replication and use the same transport, by default, all of the site links are "bridged" in terms of cost, assuming the site links have common sites. If site link transitivity is enabled, which it is by default, creating a site link bridge has no effect. It is seldom necessary to create site link bridges. However, if site link transitivity has been disabled, you need to create a site link bridge manually if a transitive link is required to handle your organization's replication strategy.

... your organization's replication strategy.

If site link transitivity is enabled and connections are created between sites that how to get windows vista for free span firewalls, replication errors will occur if the firewall allows packets to travel only between specific domain controllers.
To create a site link bridge, complete the following steps:
1.Click Start, point to Administrative Tools, and then click Active Directory Sites And Services.
2.Open the Inter-Site Transports folder and right-click either the IP or SMTP folder,and then click New Site Link Bridge.
In the New Object-Site Link Bridge dialog box, shown in Figure 5-15, type a name for the site link bridge in the Name box.
4. In the Site Links Not In This Site Link Bridge box, click two or more sites to connect, and then click Add. Click OK.
If site link transitivity is enabled, which it is by default, this procedure is redundant and has no effect.
To disable site link transitivity, complete the following steps:
1.Click Start, point to Administrative Tools, and then click Active Directory Sites And Services.
