How does a Skype Room System Authenticate

[Adam Berns]

So more on the woes of SrS.  I need to understand how this authenticates to SfB.  Here is what I have done.  I plug my laptop into an ethernet port.  I can easily sign into SfB on premise with the SrS account.  I take the same cable and ethernet port and plug it into the Srs, It does not authenticate (Exchange online works fine).

On internal wireless I try the same thing with my laptop and iPhone, both authenticate to SfB with the SrS account no problem.  I try the same wireless with the SrS (disabled the ethernet on the device through admin), still cannot login.

Connect to guest wireless, which goes through a different router and public DNS, everything works fine.

So does this connect like a mobile device or the regular desktop client?

What DNS records does it use, and how does it authenticate, through Access Edge, or internal?

Hi Adam. Just to let you know, it works for me (SRS v2 using Logitech SmartDock and Extenderbox) and we're running Exchange 2016 on-premise but SfB Online in O365. Doesn't help you much but I did exactly the same, tried everything on my laptop, just changed the Ethernet port to the Extenderbox. First time, it failed, but at reboot it worked. I assume you've checked you're getting IP-address and Internet connectivity on the SRS?

Same URL/IP should apply as regular clients. Some tips from this PowerPoint:

- Lync Connectivity Analyzer - Validate credentials and connectivity Certificates

- Ensure that any certificate used by Exchange or Skype for Business are trusted

The answer depends on which products you are asking about.

- Lyncdiscover with SIP Registration for Lync/SfB

- Autodiscover with EWS for Exchange

Skype Room System (v2)

- Lyncdiscover with UCWA registration for SfB

- Autodiscover with EWS for Exchange 

Surface Hub

- Lyncdiscover with UCWA registration for SfB

- Autodiscover with ActiveSync for Exchange

Hello Jeff
I think i have the same issue with my Skype Room System (v2) and the SFB W10 app. To connect it to the O365 cloud, i have to switch back to admin profile, open an edge browser to check connectivity and launch back the SFB SRS2 app. Then i got connected until the next disconnection.
