This is important because this lets the client machine know whether it is logged in internally or externally. Edge Server) connectivity. The first SRV record would be for internal client logins and the second one is for external (i.e. First, we see that the first two queries are for SRV (service locator) records. If we look at these DNS queries we notice a few things. I wanted to show how the Lync client automatically finds its servers for logon purposes.

You must have Outlook 2011 for Mac. You must have a hosted Lync 2013 account with Sherweb.![]() However, on the Google App store, I have read posts.from others complaining of the same thing. We use Lync 2013.So, this issue the the Microsoft “Lync Server Remote Connectivity Test” service could well be an issue with the Reverse Proxy (in our case IIS+ARR), rather than the Edge or FE (actually a Standard Edition)?Although I said that we are NOT seeing any log-in issues on ANY device, I am seeing some odd behaviour on Android devices in that after the devices sign in (OK), but then keep loosing connectivity often (showing a ‘Connection Timeout’ error, saying that the server is either temporarily unavailable or busy), only to then re-sign in. In fact, the initial Registration attempt is accepted straight away by the Front End.Hey Frank, I appreciate the response. For more info, please see me post here ( ).It also interesting to note that a mobile device doesn’t appear to go through the same process. The Lync Server Remote Connectivity Test never gets past the “unauthorized” response from the Front End, and fails after 20 attempts, although I can’t capture the Web Ticket info in the same detail on the Front End, even when enabling the WebTicketAuthLib in the logger. I was never satisfied with the simple answer I kept seeing that was, “this is normal”! I also wondered why I was not capturing the same info on a SIPStack log taken from the Front End, however, can I ask where the Web Ticket component is tied to in relation to an external user logging in via an Edge? Is this directed through the reverse proxy to the Front End, or via the Edge?My reason for my asking is that whilst I’m NOT having any issues with any client logging in from any device, I am having issues in testing my deployment via the ‘Microsoft Remote Test Analyser’ service for the “Lync Server Remote Connectivity Test”, and perhaps some issues on mobile devices (Android) that seem to time out occasionally. Create booklet in word for macIt’s just that this particular log shows only a short lived connection. Calls and IMs can be made and received, and sometimes the timeout doesn’t happen for a while (say 10 or 20 mins). This happen on both wireless and GSM connections, but I haven’t see this on iOS or Windows Phone devices.Still, I would like to get the Microsoft service to work to ensure that I have nothing else going on that is wrong.Hey Frank, I have checked the ARR RP Config and can’t seem to see anything wrong – looks like all points to 4443 (check out , which is the output (edited) from ‘appcmd.exe list config /section:webFarms’).The specific log from the Android device above was a particularly short time out – it isn’t always like this. You can see HTTP Connection error and timeouts (approx 11:10) and “errorCode=E_ConnectionTimeoutError” logged, with it eventually cleared a few seconds later. I have another test Lync 2013 setup based on Windows 2008R2 servers, but this seems to be fine – and I can see on the FE the Microsoft service attempt two registrations and then connects on the third.In the faulting domain, I do/did have additional GPOs set taken from the Security Compliance Manager (SCM), which does set NTLM to v2 (policies “Network Security: Minimum session security for NTLM SSP based (including secure RPC)” and “Network Security: Minimum session security for NTLM SSP based (including secure RPC) servers”) plus others, and this does lead to Lync complaining about NTLM mismatches, but it doesn’t stop any of my client logging in normally, and even if I unlink the entire set of GPOs, the Microsoft service still can’t authenticate (just the NTLM mismatch errors disappears).I am absolutely at a loss to understand what might be happening. Still, the Microsoft remote test service just can’t authenticate at all. The Android Mobile client can still register OK, but iOS fails. In the Lync CP, under “Security” for both “Register” and “Web Service”, I disabled ‘Certificate authentication’, Now, when I check the UccApilog for a Desktop client, I can see the client use Kerberos during registration (Proxy-Authorization: Kerberos qop=”auth”) when inside the firewall, and NTLM (Proxy-Authorization: NTLM qop=”auth”) when registering via the Edge.
