pbrooksuk just checking if there's any progress or updates? please don't forget to mark helpful replies.
- Hey Dave,
It's good to know that 389 is necessary for an AD client to function.
I may look a bit deeper if I can pin various operations to services, or if the inbuilt ruleset already does this.
Or do all of those services, go via the same executable?
