So I have been looking into why some user to port information is being retrieved by UDT for some users and not others. I have found that the users were in the same location/subnet and residing on the same switch. Upon further investigation I found that this is due to the PC's that don't have the User to PC/Port tracking have static IP addresses assigned. Is this a known issue? I imagine that it is due to the DHCP Discover process being cut out of the picture and therefor the events aren't on the DC for it. I imagine if I want this information I will need to create reservations for all those machines? Kind of a pain for a work around. Anyone else see this issue?
