hi
plz go through attached screenshot. I am getting RPC server unavailable in my exchange server whenever trying to create new user, trying to open any user properties, trying to open exchange tasks. rpc-error.JPG
Is that server (on which Exchange is installed) a DC?
If not, or if there are other DC's the server is using, i'D first check the firewall on those. It should allow for everything from exchange server. If you can, disable it at all, even just to test (and disable even the Exchange server's firewall, if u can.).
Are there DC Orphan records in your domain? Did you demote a DC in the past, when EX was working?
Did it demote successfully?
If not you should look for removing that orphan DC record BEFORE going on with that exchange case. Results in a domain with such problems are unpredictable.
