To deploy Microsoft Lync Server 2010 communications software, you must create Domain Name System (DNS) records that enable the discovery of clients and servers, and, optionally, support for automatic client sign-in if your organization wants to support it.
Lync Server 2010 uses Domain Name System (DNS) in the following ways:
- To discover internal servers or pools for server-to-server
communications.
- To allow clients to discover the Front End pool or Standard
Edition server used for various SIP transactions.
- To allow unified communications (UC) devices that are not
logged on to discover the Front End pool or Standard Edition server
running Device Update Web Service, obtain updates, and send
logs.
- To allow external servers and clients to connect to Edge
Servers or the HTTP reverse proxy for instant messaging (IM) or
conferencing.
- To allow external UC devices to connect to Device Update Web
service through Edge Servers or the HTTP reverse proxy and obtain
updates.
