Topic Last Modified: 2011-04-05

This topic describes the infrastructure and software requirements that are specific to publishing a topology, whether by using Topology Builder or the Lync Server Management Shell command-line interface. These requirements are in addition to the general operating system, software, and permissions requirements applicable to all Microsoft Lync Server 2010 administrative tools. Ensure that you satisfy all administrative tools requirements before you publish a topology.

• You must run Topology Builder on a computer that is joined to the same domain or forest of the Lync Server 2010 deployment you are creating so that Active Directory Domain Services (AD DS) preparation steps are already completed, enabling you to use the administrative tools on that computer to successfully publish your topology.
  
  

  Note:
  For details about preparing AD DS, see Preparing Active Directory Domain Services for Lync Server 2010 in the Deployment documentation.

• The computers defined in the topology must be joined to the domain, except for Edge Servers, and in AD DS. However, the computers do not need to be online when you publish the topology.
  
  
• The file share for the pool must be created and available to remote users.
  
  
• In order to publish an Enterprise Edition Front End pool, the SQL Server-based Back End Server must be joined to the domain in which you are deploying the servers, online, and configured with the appropriate firewall rules to make it available to remote users. For details about specifying firewall exceptions, see Understanding Firewall Requirements for SQL Server. For other details about configuring SQL Server, see Configure SQL Server for Lync Server 2010.
  
  

  Note:
  Standard Edition server has a collocated database that will accept the published configuration. You must first run the Prepare first Standard Edition server setup task in the Lync Server Deployment Wizard.

• If you run Topology Builder on a computer where you plan to later install Lync Server, then you must install the Microsoft SQL Server 2005 backward compatibility components by running the first setup task in the Lync Server Deployment Wizard before you publish the topology. For details, see Install the Local Configuration Store or Install the Standard Edition Local Configuration Store.
  
  

  Note:
  You do not need the Microsoft SQL Server 2005 backward compatibility components to publish the topology if you run Topology Builder on a dedicated administrative console or if you run Topology Builder on a computer where Lync Server is already installed. (Lync Server setup automatically installs the backward compatibility components along with other component files required by Lync Server.)
