Lost Admin password

First stop the winroute engine, then go to the registry editor by going to the start menu -> run and type 'regedit'. Proceed to hklm/software/kerio/winroute/user/0. Delete the '0' key. Then select the 'user' key and export it to a file. Then go back into regedit to hklm/software/kerio/winroute. In the right hand window you'll see 'adminuseradded'. Modify it to '0'. Then start the engine and log in as admin with no password. Then stop the engine. Once the engine is stopped import the registry file and restart the engine.
