Hello, I am trying to delete my certificate authority, so I'm cleaning up the AD as recommended by the Microsoft doc. In "active directory sites and services", more exactly in AIA, I deleted SOP16 was my certificate authority. But I also see there SSGEX10 which is my exchange server 2010. I do not know if I should remove or not ssgex10 server Authorities. Does that have exchange 2010 could tell me if the server also appears here in "AIA"? like this : http://img10.hostingpics.net/pics/687089exchange.jpg http://img10.hostingpics.net/pics/511738exchange2.jpg thanks
