Lync 2013 DNS Records
This Blog we will see what are all the DNS Records needs to
create for Lync Deployment.
I could see so many quarries on TechNet article about
Creating Dns entries.
Overview
DNS A Record
DNS SRV Record
What is A Record?
The record A specifies IP address (IPv4) for given host. A
records are used for conversion of domain names to corresponding IP addresses.
What is DNS SRV
Record?
A Service record (SRV record) is a specification of data in
the Domain Name System defining the location, i.e. the hostname and port
number, of servers for specified services.
Here is the List of DNS Records which you need to create

What about pool pairing? If I have two pools in a paired pool configuration does each pool get it's own A record or does the lyncdiscoverinternal A record contain the FE servers from both pools? If the FE server you connect is not in the pool for your account does it redirect to the other pool?
ReplyDeleteHi, according to the TechNet article _sip._tls.domain.com should pointed to 443 tcp port:

An external interface for your Access Edge service. This SRV record is required for Skype for Business Server 2015, Lync Server 2013, and Lync Server 2010 clients to work externally. You'll need one for every domain with Skype for Business users.

How can you have an A record for a Front End Pool. A records need IP address, not FQDN.
ReplyDeleteCreate Host A records based on your number of front end servers for front end pool and point it to your front end servers
