Hi
we did another approach since we run ~1000 domain controllers.
Especially in the morning the controllers are under heavy load and the plugin outputs a lot of errors since replications take a long time or even fail in the first place, and this generates huge error plugin outputs. So we ditched that for a textfile which is placed in a special subdirectoy in SYSVOL. This file then must have a certain size and a certain age. If the file is not there or too old, we assume that replication is not working.
