I have 3 2008R2 Servers set up as Remote Desktop Servers. Before I add them into a Network Load Balance configuration, all printers show as online. as soon as i add each to a NLB configuration, 4 HP Laserjet 2015 printers go offline and can not be pinged from the servers. The printers could be pinged and printed to before joing the NLB and can be pinged from any other machines. Get Destination unreachable.
