Lync client iOS "The server name is incorrect..." using autodiscover

    General discussion

  • Lync Client for iOS

    Symptom:  With autodiscover enabled the client responds with a ‘The server name is
    incorrect.  Please check it and retry.”


    Configuration of iOS client withurls works.  Both autodiscover files (root & domain) obtained
    via Safari look OK to me.

    Results from http://www.testocsconnectivity.com succeed.

    Configuration info:

    Two FE servers DNS load balanced.

    Web services (simple urls, etc.) load balanced behind F5 LTM  (v10.2).  Setup using cookie persistence and encryption both to and from the vip.

    Get-CsMcxConfiguration |fl

    ExposedWebURL:   External


    Split DNS.

    External web services URL is published externally via TMG.

    External cname for lyncdiscover.domain.com points to external web services DNS A record.



    lyncdiscover.domain.com has been added to certificates and re-published on FE, LB and TMG.

    I must be missing some elementary element releative to autodiscover. Any ideas?

  • I think I've exhausted all of the troubleshooting I can do with out help.  I've opened an incident with Microsoft.

    However, while perusing the Permier support site, I noticed an update was released a few days ago for Lync, which includes a possible fix (kb 2493736) for this specific mobility issue.  And a few others.  I'm planning on installing the updates this weekend.  I'll report back next week.

  • Oh... sorry.  http://support.microsoft.com/kb/2493736 contains an update for the mobility service.

  • I have had the same experience and have applied all of the recent updates and verified that the service is reachable via a web browser and through the http://www.testocsconnectivity.com/ site.  Not sure what the issue is now.  Also noticed that Federated contacts are now having presence issues where presence is shown as "unknown" until a user is selected for a conversation at which time their presence is shown.  Equal experience as a Lync user inside and outside the firewall.  Weird.

  • The March updates, referred to as CU5 did not correct the issue.

    I contacted MSPSS, who requested I uninstall and start over.

    After doing so autodiscover was working as expected.

    So that part is done.

    So clients are able to login using Auto-Detect Server .

    Here are the steps to re-install... in my case anyway.

    From Control Panel, select uninstall a program.  Select Lync Server Mobility Service.

    Then:



    1.   Log on to the computer as a user who is a member of the CsAdministrator group.<o:p></o:p>

    2.   Download the latest installation package from the Microsoft Download Center and extract it to the hard disk.<o:p></o:p>

    3.   Copy McxStandalone.msi to C:\ProgramData\Microsoft\Lync Server\Deployment\cache\4.0.7577.0\setup.<o:p></o:p>

    4.   Start the Lync Server Management Shell:
    Click Start, click All Programs,
    click Microsoft Lync Server 2010, and then click Lync Server Management Shell.<o:p></o:p>

    5.   Run C:\Program Files\Microsoft
    Lync Server 2010\Deployment\Bootstrapper.exe.

    Then reboot the FE's and test.

    The other steps covered in the Mobility Guide were still in place, so I didn;t need to rerun those.

  • Dude. If you called MS support on this ... can you please share the answer for the rest of the community?  That'd be really helpful as we try to support our own systems and support others.

  • when you go to your EDGE server ... can you please look and see if you have any errors in the event logs?  Typically, if you have problems - in the event log will show some clues.  Please report back.
