I just brought up a new Exchange 2013 SP1 Server on a 2012 r2 domain which gave me a real hard time about completing the install which required cleaning out some objects from adsiedit.msc in order to have a clean install run.... Or so I had thought after bringing the server up and started down the checklist I found that there are several servers listed under the server list in the EAC that do not exist and there are either no databases associated with them or listed as unknown. They are also not part of a DAG.
3 of the names were from failed installs where I just deleted the server from esx 5.1 and cleaned up the ad objects using adsiedit.msc or so I thought as well as a what looks like a failed 2010 server install from a another admin previous to me being here.
What is the best/safest way to remove these servers from the server/database list?
