Summary
Microsoft Lync Server 2010 communications software supports computer networks that are designed to meet the needs of a variety of organizations. These organizations can be small, medium, or large, and they have varying requirements for performance, high availability, and scalability. In this article, we will focus on the needs of a very small organization, consisting of a single Active Directory domain.
More Information
The simplest Active Directory topology supported by Lync Server 2010 is a computer network that is known as a single-domain forest. The following figure illustrates a Lync Server 2010 deployment in a single-domain Active Directory topology.

Hardware Recommendations for Servers Running Lync Server 2010
Microsoft Lync Server 2010 communications software server roles and computers running Lync Server administrative tools require 64-bit hardware. The specific hardware that is used for Lync Server 2010 deployment can vary depending on size and usage requirements. For more information, see Server Hardware Platforms.Operating system requirements
- Lync Server 2010 servers are supported on Windows Server 2008 x64 and Windows Server 2008 R2 server operating systems.
- Microsoft Lync Server 2010 communications software administrative tools are installed by default on the server that is running Lync Server 2010. However, you can install administrative tools separately on other computers that are running Windows operating systems. For example, you can use a client computer running Windows 7 as an administrative console for planning purposes. For more information, see Server and Tools Operating System Support.
Certificate Infrastructure Support
By default, network communications in Lync Server 2010 are encrypted. Certificates are required for all internal servers that are running Lync Server 2010. Virtually all Lync Server data is protected on the network. This is accomplished by requiring all servers to use certificates and by using Kerberos authentication, TLS, Secure Real-Time Transport Protocol (SRTP), and other industry-standard encryption techniques, including 128-bit Advanced Encryption Standard (AES) encryption.
