Hi Manish,

You need check if you have the records in the DNS zone

For all clients except for the Lync Windows Store app During DNS lookup, SRV records are queried and returned to the client in the following order:

1. lyncdiscoverinternal.<domain>   A (host) record for the Autodiscover service on the internal Web services

2. lyncdiscover.<domain>   A (host) record for the Autodiscover service on the external Web services

3. _sipinternaltls._tcp.<domain>   SRV (service locator) record for internal TLS connections

4. _sipinternal._tcp.<domain>   SRV (service locator) record for internal TCP connections (performed only if TCP is allowed)

5. _sip._tls.<domain>   SRV (service locator) record for external TLS connections

6. sipinternal.<domain>   A (host) record for the Front End pool or Director, resolvable only on the internal network

7. sip.<domain>   A (host) record for the Front End pool or Director on the internal network, or the Access Edge service when the client is external

8. sipexternal.<domain>   A (host) record for the Access Edge service when the client is external

you can follow the next documentation.

If you have this tou can sahre part of the Skype client Log's
