IIS requirements for Front End pools and Standard Edition servers

Topic Last Modified: 2012-06-19

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:

To enable users to download files from the Address Book Service
To enable clients to obtain updates
To enable conferencing
To enable users to download meeting content
To enable users to expand distribution groups
To enable phone conferencing
To enable response group features

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

On Front End Servers or Standard Edition servers to support mobility functionality, such as instant messaging (IM) and presence, on mobile devices
On Front End Servers or Standard Edition servers and on Directors to enable mobile devices to automatically discover mobility resources

Note:
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:

Important:
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.

You must use the IIS administrative snap-in to assign the certificate used by the IIS web component server.
