I removed 6.5.19 and put 6.0.7 on this Server which required .NET 3.5 and some extra boxes ticked for ISS role/features. 6.0.7 worked OK, could add printers 1by1 again and the printer info page loaded OK.
I upgraded to 6.5.19 after this and now get this instead of a blank window when I click a device, a slight improvement...
We're having a problem with new C3070, C3570, C4570 and other devices where the CWW Discovery Scans are causing devices to 116-324 error and crashing them. We have to visit each device and physically reboot them.
I've turned the Discovery Scans Off and it's stopped on our 6.0.7 Server. I can add devices one by one via the Add a Device box.
I've setup a new Server running 6.5.19 and have it all working with two issues.
1. Adding via the add Devices box is causing devices to 116-324 Fault and need a reboot....
2. Once it's then added, and I click the Printer / Device it just loads a blank page... no printer info ever appears.
