My SOE extension crashed. Now it does not appear in extension list, but does so in Capitabilities of a service. Services with it give error on run. When I try to add it anew to the server, I get "An extension with name 'xxx' is already registered for service type 'MapServer'" error.
ArcGIS Installation 10.1. To default location.
Note: Solutions I got on the internet: a. Restart ArcGIS Server from Task Manager( restarted many times everything that can be restarted -> no effect ) b. Remove and re-install ArcMap Server ( can't do it now, may be as last resort)
