user connections

Hi

I want to set a maximum number of user that can simultaneously be connected to the MS SQL server.

I used this script but that it doesn't work.

EXEC sp_configure 'show advanced option', '1'
RECONFIGURE
EXEC sp_configure

EXEC sp_configure 'user connections', '1'
RECONFIGURE WITH OVERRIDE
EXEC sp_configure

Does somebody can show me how to set a maximum of user connections?

EXEC sp_configure 'user connections', '0'
RECONFIGURE WITH OVERRIDE
EXEC sp_configure

What's your license type?
