[cannot get user login notification]

it was a group policy.  We didnt have the user logon monitor checked in the group policy because we didn't want to get notified about every computer in the group.  We simply turned it on for the pcs we wanted and it was never turned off by group policy.  We just turned off the group policy.

[cannot get user login notification]

I have several agents that will not send user login and logoff notifications.  It will send other notifications.
