I had a gateway server once and without uninstalling the gateway server role i reformated the server, and now i can not delete the gateway server from "Management Servers". The error is: System.ArgumentException: The management server is part of the communication topology and cannot be deleted. How can I delete or clean this management server ? Those who are skilled in combat do not become angered, those who are skilled at winning do not become afraid. Thus the wise win before the fight, while the ignorant fight to win.

I have seen this address before and did them all but still i cannot delete the stale gateway server.Those who are skilled in combat do not become angered, those who are skilled at winning do not become afraid. Thus the wise win before the fight, while the ignorant fight to win.
