Dune Real Vision 4K network problem - SOLVED

[Yarc]

Hi all.

I’m a happy owner of a Dune Real Vision 4K, but I had an issue trying to connect to it over my local network from my Windows 10 desktop.  However, I could connect from my laptop which meant it was an issue on my desktop and not the Dune unit. 

The Windows error was an unhelpful ‘Windows cannot access \\xxx.xxx.x.xxx Error code: 0x80004005, unspecified error.

To cut a long story short, I examined the Windows Event logs on my laptop and desktop (both Win10 machines) and discovered that unauthenticated guest logins were not allowed on my desktop.  There is a required registry setting to enable/disable this feature.  Strangely, it was absent on my laptop and so Windows defaulted to allowing these logins. On adding this registry setting to both machine (no reboot required) I had communication!  I know it’s a legit registry setting because my laptop’s event log mentioned it was missing.

To solve my issue I had to run Registry Editor, navigate to:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters

Then modify the value called AllowInsecureGuestAuth  to 1

I had to add this value to my laptop which removed the warning in the event log that it was absent!

I hope this may help people who may stumble on this.  It took me a while to solve.

I would not call it Solved but Bypassed.

It has the attention of Dune. There a DSF to put a default/fixed UID + PWD on it (=a Dune bypass).

Great to hear that Dune are aware. I think there should be a UID+PWD and was surprised there was not one to be honest.  Although my solution is valid in terms of using a correct registry setting, it is, as you say, a work-around Dune's omission.
