I created a sensor on a local probe to monitor a DC in a different site (but same domain) which worked OK but suffered occasional false downtime alerts due to network blips. I have now installed a remote probe on the DC which does not suffer the same problem. However, the Active Directory Replication Errors sensor has never worked on the remoter probe. The same sensor worked OK on the local probe.
I have checked the user documentation and found that this sensor requires .NET 2.0. I have checked the remote server and .NET 3.5 is installed, which includes the 2.0 framework and there are no pending updates for .NET 2.0.
I have this sensor working correctly on 2 DCs in my local site, using the local probe. I have read the documentation which states that the sensor makes a list of all DCs and checks them all.
So my first question is, do I need this sensor on all 3 of my DCs, or will 1 suffice.
If I do need this sensor on all 3 DCs (e.g. for best practise) then can you advise how I can resolve the issue on the remote DC to make it work.
