IIS Requirements for Front End Pools and Standard Edition Servers

 

Topic Last Modified: 2012-10-18

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:

  • To enable users to download files from the Address Book Service

  • To enable clients to obtain updates (for example, Microsoft Lync 2010)

  • To enable conferencing

  • To enable users to download meeting content

  • To enable unified communications (UC) devices to connect to Device Update Web service and obtain updates (for details, see Updating Devices in the Planning documentation)

  • 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 Microsoft Lync Server 2010 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. For details, see Installing the Mobility and Autodiscover Services.

Lync Server 2010 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 2010 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 https://go.microsoft.com/fwlink/p/?LinkId=216888.
