TLS Outgoing Connection Failures

Whilst checking a event viewer on a Lync Front End today I noticed.




The above message has the right host name but WRONG IP address, after checking DNS I found four (4) entries for the Edge server.  three (3) entries with IP address for the external NIC of the edge.


So I figured that the external NIC was trying to register with DNS.


From the NIC properties select "Internet protocol Version 4 (TCP/IP)


Select Advanced


Select the DNS tab, then un-tick the "Register this connection's address in DNS"


You may see the initial error message appear in the event view one (1) more time before it stops reporting.
