Script Info: Test ADObjectReplication

SYNOPSIS

Monitor AD Object Replication

DESCRIPTION

Each run of the script creates a unique test object in the domain, and tracks it's replication to all other DCs in the domain.

Script Type:

This script runs from a source server, determines the DC with the PDCE role, targets it, and creates a disabled computer object in the 'default computer' OU or CN.

By default it will query the DCs for about 60 minutes.

If after 60 loops the object hasn't repliated the test will terminate and create an alert.

The test object created in the run will be deleted at the end of the test cycle.

The script will look for other objects matching the same name format in the OU/CN, in case they were not deleted during the previous run, and alert if they exist.

If the PDCE is offline, the test will terminate.

If other DCs are offline, an alert will fire that they can't be reached. This only alerts on the 10th cycle of the test to prevent filling up your inbox.

The 17015 Job Output Event will include the duration metrics for the run.
