title: DNS SRV record changed for service discovery but mobile Office apps are still calling old server
body: <p>I'm working on a custom AD RMS solution that allows opening of protected documents in Microsoft Office apps on MacOS and iOS devices. It's based on Microsoft Mobile Device Extension and a custom authorization server built with Owin and Katana.</p>
  
  <p>The DNS SRV record was originally set to a development server. Now that the application is working fine, we've changed the DNS SRV to a production server (a several weeks ago already).</p>
  
  <p>The problem is that our devices on servicediscovery calls are still reaching out to the old development server.</p>
  
  <p>I've flushed their DNS cache, reset the app data, reinstalled the apps - nothing seems to be working, the Office apps always call the old server.</p>
  
  <p>The new DNS SRV record should be already replicated across DNS servers.</p>
  
  <p>I'm completely stuck at the moment and I cannot put it in the production as the production server never gets "discovered" and called. Did anybody have a similar issue or some deeper understanding of how the Microsoft ADAL service discovery works on mobile devices to provide me a hint of a solution?</p>
