For Standard Edition servers and Front End Servers, and Directors, the Microsoft Lync Server 2010 installer creates virtual directories in Internet Information Services (IIS) for the following purposes:

Lync Server 2010 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 2010 files will be deployed to this drive as well. For details on how to relocate the INETPUB deployed by Windows Server Manager when installing IIS, see
