We run NDPS, and I cant seem to get event popups on client machines. I
have ticked all relevant boxes in the printer object, and the user has a
default server. Event Notification is enabled on the Broker.

I need to 'Pause Input' on several printers, though I want a popup to
notify users that their job hasn't printed due to this. I do get a EventID
6161 entry in the system Event Viewer, but I want a popup for it.

I did enable the Messenger Service on the local computer, but that hasn't
helped. The workstations are running Windows 2000 SP4.

We run an IP only network.
What things can I check to troubleshoot this problem.
