Automating replication testing

Building on the recent post about testing replication I though a bit more automation was needed. Lets create a function to discover the domain controllers

function get-DomainControllerNames {
 $dom = [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
 $dom.FindAllDomainControllers() | select -ExpandProperty Name
}

We then use a simple pipeline to produce a nicely formatted report

get-DomainControllerNames |

foreach { test-replication -computername $_ } |

Format-Table -Property SourceDsACN, NamingContextDN, Last* -GroupBy DomainController –AutoSize 

   DomainController: DC02.Manticore.org

SourceDsaCN NamingContextDN                                LastSyncAttempt     LastSyncSuccess   
———– —————                                —————     —————   
SERVER02    DC=Manticore,DC=org                            06/02/2012 10:53:45 06/02/2012 10:53:45

SERVER02    DC=ForestDnsZones,DC=Manticore,DC=org          06/02/2012 10:07:02 06/02/2012 10:07:02

   DomainController: SERVER02.Manticore.org

SourceDsaCN NamingContextDN                                LastSyncAttempt     LastSyncSuccess   
———– —————                                —————     —————   
DC02        DC=Manticore,DC=org                            06/02/2012 10:03:17 06/02/2012 10:03:17

If you have a very large number of domain controllers this may take a while to run. In that case split the domain controller list into a number of CSV files and work from those.
