I have a Live Communications Server 2005 that is up and running with a named instance of subdomain.domain.com<br />
<br />
I already had a DC and my Active Directory setup and populated prior to setting up this server. &nbsp;I need to know what configurations/changes I need to make so that when a user that has a valid SIP in AD logs on to his/her windows machine they don't also have to log into their office communicator; I would like them to be authenticated to the LCS based on having successfully authenticated to AD.<br />
<br />
I am new to LCS so any and all help is greatly appreciated.<br />
<br />
Thank you,

Live Communications Server 2005 Windows Authentication

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
