We have version 10.1.1

On initial install 10.1.0 is installed. 10.1.1 comes down once the
device has registerred. Everything was fine until recently.

Now we are getting more and more machines which display unmanaged like
below:

Device Name: unmanaged
Device Status: unmanaged

Management Zone: unavailable
Server DNS: unavailable
Server Address: unavailable

The user at times cannot even login. Therefore 10.1.1 never gets
distributed.

You can restart many times with result. Then radomly the
zac reg https://servername works. It's like russian roulette.

If the machine has been registerred in the past, sometimes deleting the
old device name in the devices list works. Sometimes not.

I see these issues on a regular basis. We re-image about 20 computers a
day and see this about 2-3 times.

Just a start about how to rectify or mitigate this would be very
helpful. My techs are getting very stressed that we cannot delevelop a
process thats consistent with dealing with this issue.
