lsrvdown utility is used to shut down the named license server. lsrvdown can be used as:
lsrvdown host-name
on Windows 2000/XP/Server 2003/Vista/Server 2008 and UNIX.
Here, host_name specifies the name of the computer that is running the license server that you want to shut down.
lsrvdown can be run from the operating system command prompt by an administrative user on a client or license server computer. On UNIX, only the user logged in as “root” can use lsrvdown. On Windows 2000/XP/2003/Vista, any user with administrative privileges may use lsrvdown unless the license server was started by a user logged in as Administrator, in which case only Administrator can shut the license server down. The computer on which you are running lsrvdown must be in the same network domain as the license server computer.
