When you deploy a Microsoft Lync Server 2010, Director or a pool of Directors, we recommend that you use Automatic Client Sign-In as a best practice. For details about how to configure DNS servers for automatic client sign-in, see DNS Requirements for Automatic Client Sign-In in the Planning documentation.

If you have already deployed Automatic Client Sign-In, see the following sections to configure it on your Director(s).

Single Director Instance

If you already have Automatic Client Sign-In deployed and it is pointing to a Standard Edition server in an Enterprise Edition Front End pool, you need to change the DNS SRV record to point to the Director.

Director Pool

If you already have Automatic Client Sign-In deployed and it is pointing to a Standard Edition server in an Enterprise Edition Front End pool, you need to change the DNS SRV record to point to the Director pool.
