Monitoring Replication

The WMI Replication provider is another good example of how Microsoft is leveraging WMI to help with monitoring Active Directory. Like the Trustmon provider, the Replication provider is only available with Windows Server 2003 and is contained under the root\MicrosoftActiveDirectory namespace. It provides classes to list the replication partners for a domain controller, view the supported Naming Contexts for a domain controller, and also see the pending replication operations.

Table 29-8 contains some of the more useful properties for the MSAD_ReplNeighbor class, which represents a replication partner (or neighbor) for a given domain controller.

Table 29-8. Useful MSAD_ReplNeighbor properties

Property	Description
`IsDeletedSourceDsa`	Boolean indicating whether the source DC has been deleted.
`LastSyncResult`	Number representing the result of the last sync operation with this neighbor. A value of 0 indicates success.
`NamingContextDN`	DN of the Naming Context for which the partners replicate.
`NumConsecutiveSyncFailures`	Number of consecutive sync failures between the two neighbors.
`SourceDsaCN`	CN of the replication neighbor.
`SourceDsaSite`	Site the replication neighbor is in.
`TimeOfLastSyncAttempt`	Time of the last sync attempt.
`TimeOfLastSyncSuccess`	Time of last successful sync attempt.

There are actually several property methods available other than what is shown in Table 29-8, so in the following example, we will enumerate ...
