I configured a database availability group and set 2 domain controllers as a file share witness and alternate witness (one at my office and one at the co-location facility I have). Prior to doing this, I added the Exchange trusted subsystem group to the builtin\administrators group.
Whenever I run set-databaseavailabilitygroup, I get:
WARNING: The Exchange Trusted Subsystem is not a member of the local Administrators group on specified witness server
if I open up active directory users and computers on either of the domain controllers, I can see exchange trusted subsystem is listed in built-in/administrators. Why do I keep seeing this message?
