disable enable logons - forum topic by mikesteeves

We have a need to selectively disable logons as part of our D/R test.  I know how to disable ALL logons but we would like to disable logons and then enable only specific groups over a period of time throughtout the test.  We are considering revoking Roles for those users and then granting the roles back to them but I wanted to know if there was a more graceful way to accomplish this task.
Thanks,   Mike
