Multipoint Server issues

[joe90bass]

We are having some annoying issues with our Multipoint 2011 premium setup and wondered if anyone else had come across the same issues. I have a call in with MS PSS, but they are not very quick in responding of late.....

 

We have 8 Multipoint servers - i7, 8GB RAM, SATA drives. 6 servers have 3 graphics cards and run 8 clients, 2 servers have 2 Graphics cards and run 6 clients. All connect to HP T150 zero clients for keyboards, mouse and audio, the monitors are direct connect to the graphics cards.

On power up some stations randomly need remapping via the press key ‘x’ screen, but that doesn’t work I actually need to unplug and reconnect the USB lead on the T150 for them to kick in. One multipoint today needed 4 out of 8 stations remapped this way. To clarify they have all been setup this isn’t inital setup! Some users also randomly have no Internet access or IE takes a long time to load.

 

I have now removed the Graphics cards out of the two six user MPS to see if this setup works better, and have USB connected them for display to the T150. One seems to work great, but the other will not pick up the keyboard and mouse from the T150 on the primary station

 

All MPS are installed from the same image.

 

We have an inspection in 4 weeks, and I'm not confident that the two classrooms these are in will be reliable enough to use for staff at this time..........

Its not that windows is putting said devices into sleep mode and the signal from keyboard/mouse is not waking them up again but unplug/plug back in is?

 

Check in device manager for the USB hubs and properties - power management.

That was one of the suggestions from MS, on the MPS with the graphics cards there's definitely no option as there's no drivers installed the T150s run as generic hubs (apparently you need the drivers to enable this option, though on the two with drivers isntalled I still haven't found this option), also bizarrely if I install the driver for the T150 they BSOD as there seems to be some clash with the ATI drivers. The issue is on powering up the MPS first thing in the morning, so they should be waking up anyway! I have looked at all other power options and where possible set them to be always on

 

Thanks

I know it sounds a little stupid, but are you installing the drivers in Normal, or Maintenance Mode? I find that sometimes drivers applied in Normal mode, don't seem to associate properly over reboots..

 

The other thing that I'd check, is how the USB devices are spread over hubs. In the past, there has been a problem with devices being power hungry and pulling more from the root hub than it can handle (most hubs are happy with <500m A per port).

Plus one for power, try hooking them in via a powered hub. We had the slow down on IE but only for admins and it was resolved by setting the mps sessions to share an IP, it seemed to be a network discovery type issue.

 

I'd also look at more ram, unless they are just using one web page at a time 8gb for 8 clients is a little tight.
