Skype for Business meeting displays black screen and pause icon
- So, we ended finally found this https://support.microsoft.com/en-us/help/3150900/black-or-frozen-screen-when-you-share-your-screen-in-skype-for-busines We don't know how or when but several of our users had that registry key. When a user w/out that key was initiating a screen share it would pause (black screen with white pause icon in top left). If a user with those registry keys initiated the screen sharing it works because those w/out the reg key would I guess "fall back" to RDP protocol. So we're working on collecting all machines in our firm that have that registry key and removing.
We struggled with this for quite some time. We opened at least two tickets for this with MS, and we always were give the keys referenced in this thread. It turns out that a new ticket with MS revealed that we need to add more keys to disable VBSS in conferences. The keys we had been given disabled VBSS in P2P conversations, the new keys disable VBSS in conferences:
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Lync]
"EnableConferenceScreenSharingOverVideo"=dword:00000000
Additionally, if you use the 32-bit version of Skype for Business 2016 on a 64-bit operating system, add the following subkey:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\16.0\Lync]
"EnableConferenceScreenSharingOverVideo"=dword:00000000
Deploying these keys and hoping that this is the end of this. Although I am trying to get the MSI codebase fixed to be able to use VBSS reliably rather than having to hack the registry to revert to RDP (not holding breath).
