Hi ,

       I have setup lync server 2013 with pre - configured vhd files . I'm able to login to lync using client application. But i can't login using UCWA sample application .

I'm getting auto discovery failed error when i try to login.

Can anybody help me to solve this issue.

Thanks in advance.

have you setup the dns entry for lyncdiscoverinternal.sip.domain?

Hi veera.veluchamy,

Is the Sip sign-in address different from the UPN?

If this is the case, you need to add the username box to allow a username to be entered separately from the sign-in address.

Theres a related article for your reference.
