I administer a network that has users constantly disconnecting their machines from the network. This makes it very difficult to verify the number that I receive from the helpdesk as to how many clients should be on the network. It also causes many machines not to get WSUS updates that are pushed during late hours of the evenening to maximize bandwidth during business hours. Is there something I can implement on the network that will not allow a user to utilize the network, even though he is a member of the network, if he is not compliant with the current WSUS updates that have been pushed?
