Recently due to my Exchange server (EX01) hanging I had to format it. Before Formatting I created new Exchange server (EX02) with a different name add it to the Administrative group and by default to the same routing group.
Once I format my real server and installed exchange again and renemed it to a new server (EX03) .
Thus Now I have Ex01, Ex02, Ex03 servers being displayed in my routing group inside members and also in servers in administrative groups.
I just want to keep EX03 which is only connected inj the network. Rest there are no servers.
