Can/How to lock users out of System when needed.

Hi Everyone, 

We are looking for a way to lock out users from using Lawson when we have to.  Sometimes we would like to have some users locked out of the Lawson apps at certain times of the day/night/weekend.  Two areas I am looking at: when we need to apply patches and when we are running our payroll process. 

We are Windows installed env.    Version 10. 

I scanned the forum and nothing really jumped out on how to do that. 

Any ideas/solutions would be helpful and appreciated.

 Thanks

Terry
