Running a Windows 2000 domain, Active Directory.
I have 50 per-seat licenses and 48 users.
As users have left the company, they are deleted off of AD.
I keep getting licensing warnings in Event Viewer on my license server that we are over the limit on our Windows licensing.
I go into license manager/Properties of server and there are users in there that have been gone for 2+ years. I revoke the licenses.
I then go into Clients (Per Seat) and delete the users there. In a couple of days, they are all back and I am over my license limit again.
I only have 1 license server in my domain.
