Load-Balancing Connection Objects






Load-Balancing Connection Objects

Problem

You want to evenly distribute connection objects between bridgehead servers in a site.

Solution

Using a command-line interface

To see what changes the Active Directory Load Balancing (ADLB) utility would make, run the following command without the /commit option. To actually make the changes in Active Directory, use the /commit option:

	> adlb /server:<DomainControllerName> -site:<SiteName> [/commit] [/verbose]

This utility is available in the Windows Server 2003 Resource Kit.


Discussion

Bridgeheads can become overloaded or end up with too many connection objects in relation to other bridgeheads in the domain. The Active Directory Load Balancing (ADLB) tool allows you to balance the load of connection objects among bridgehead servers within a site. The Windows Server 2003 algorithms are much better than Windows 2000 at load-balancing connection objects across servers, but that process happens only when new connection objects are added. You can use the adlb tool to load-balance existing connection objects more efficiently at any time.

We recommend first viewing the changes adlb would make before using the /commit option. Though the tool has matured to the point that it will typically make good decisions for your topology, it is still always good to do a sanity check to ensure adlb doesn't mess up your replication topology.
