I'm in an 2003 environment that has multiple sites- all connected by T-1s. While removing a child domain, I started poking around in sites and services. I saw that for the replication links, the costs were all different. I thought that you would only have different costs if you had different types of connections -for example, a slow DSL or dial up backup connection that would have a higher cost than the T-1. With that in mind, should I make all of these costs the same value? The replication interval for all sites is also the same. Set for 180 minutes. Thanks!
