I have deleted the app and reinstalled it and the problem persists.User inside the Corp-Network using a domain joined laptop Skype4b Client – AuthenticatingOk so the Client successfully located the frontend, now comes the fun part, authenticating against the frontend there are a number of scenarios to consider here: Well you get the idea □Back to our example let’s consider that all your DNS requirements are there, what happens then is because the new employee sitting inside the Corp network, the client will get a response for the lyncdiscoverinternal record and then will contact the frontend pool and authenticate with it.In case you did not already catch on that, skype4b try to resolve either lyncdiscoverinternal or lyncdiscover which will let the client to know if it is inside or outside the Corp-Network.Just for your information the second time the user will try to sign-in the client will go directly to the Frontend pool, not going through the whole process again unless it cannot discover the lyncdiscoverinternal or you flushed the DNS. After a windows update, I can no longer start Skype for business.Skype for business client autodiscover logicNote: in real life not all mentioned steps are conducted by the Skype for Business client.So as you see in the video, the Skype4b client is designed to search for the frontend pool using pre-coded DNS records, it gets the domain name from the user’s sip-address one in red (user sip-domain) then start adding to it pre-coded values in the following order:I did a test using a fake sip-domain to show you the logic in how Skype4b client discover the frontend IP-addresses, following screenshot is taken from MS Network Monitoring toolWhen the client cannot resolve the first DNS records it tries the second one, if not then the third if not then….Client will get back a response with two HTTPS URLs in it this is a screenshot take by Fiddler for a real life example with office 365 Client will try to locate the Auto discover services, the use of the Autodiscover services is to tell the client where is the user is homed, client does that by sending two parallel HTTP and HTTPS GET requests to the Autodiscover services running on the pool and as following: Certificate (TLS-DSK) << most preferred oneUser Inside Corp-Network with domain joined laptop:P.S I will be using the word “Pool” a lot, and by pool here I mean your frontend or director pool depending on your deployment type.So this employee we are talking about above is signing in for the first time using the Active directory username and password and the client resolved the lyncdiscoverinternal DNS record successfully, now what?Skype4b Client will try to authenticate using NTLM, which will return Unauthorized Authentication traffic will be proxy via the Edge pool to the Pool (Director or Frontend) Client authenticate successfully and get a response from the Autodiscover services with the information needed in the format of xml, below is a real life capture from my office 365 accountAnd here is a short video to show the work flow of how authentication worksSkype for business authentication overview User Outside Corp-Network with domain joined laptop:External users trying to sign in from outside the Corp-Network using a domain joined machine, lets assume that the user never signed in before and have no certificate from Lync.Lync uses two method of authentications here:Assuming that the Lync Edge and the reverse proxy servers are deployed and have no problem the authentication process will be same as scenario one but with the following differences: Client start communicating to the user’s home frontend and go through step 3-5 again Client will get a response with where the user’s home pool is.
