Testing replication
We’ve seen a few things we can do with the WMI provider for Active Directory. One of the most useful is testing replication
function test-replication{
[CmdletBinding()]
param(
[string]$computername=$env:COMPUTERNAME
)
Get-WmiObject -Namespace root\MicrosoftActiveDirectory -Class MSAD_ReplNeighbor -ComputerName $computername|
select SourceDsaCN, NamingContextDN,
@{N="LastSyncAttempt"; E={$_.ConvertToDateTime($_.TimeOfLastSyncAttempt)}},
@{N="LastSyncSuccess"; E={$_.ConvertToDateTime($_.TimeOfLastSyncSuccess)}}
}
A simple call to the MSAD_ReplNeigbor and we can test the last times the DCs attempted to synchronise and the last time they were successful
