Having difficulties after upgrading my DC from 2008 R2 to 2012 R2. Now my Exchange Server 2010 SP3 RU9 running on Server 2008 R2 SP1 was hanging at "Applying Settings..." until I stopped all the Exchange services.
Manually starting the services works, all except "Microsoft Exchange RPC Client Access". It gives me the boiler plate "..some services stop automatically...", but without it none of my OWA clients can connect.
Been ALL over the net, seems to be a pretty regular issue, but cant find anything that fixes this.
