AD Show Replication monitor not working in AD Domain Services MP 10.0.2.1
AD Show Replication monitor does not work and will always be in a GOOD state.
The reason to this behavior is the sReplicaDC variable used as an input to the PingServer function in the AD_Replication_Check.vbs script. sReplicaDC contains a space in the end.
This will make the PingServer function to always return false and not change the state on this monitor.
