For Standard Edition servers and Front End Servers, and Directors, the Lync Server 2013 installer creates virtual directories in Internet Information Services (IIS) for the following purposes:

In addition, the cumulative update for Lync Server 2010: November 2011 installer creates virtual directories in IIS for the following purposes:

If you are deploying mobility, we recommend that you use IIS 7.5. The Lync Server Mobility Service installer sets some ASP.NET flags to improve performance. IIS 7.5 is installed by default on Windows Server 2008 R2, and the Mobility Service installer automatically changes the ASP.NET settings. If you use IIS 7.0 on Windows Server 2008, you need to manually change these settings.

Lync Server requires the following IIS modules to be installed:

If your organization requires that you locate IIS and all Web Services on a drive other than the system drive, you can change the installation location path for the Lync Server files in the Setup dialog box. If you install the Setup files to this path, including OCSCore.msi, the rest of the Lync Server files will be deployed to this drive as well. For details about how to relocate the INETPUB deployed by Windows Server Manager when installing IIS, see
