This topic applies to deployments supporting Lync 2010 Lync Mobile clients only, and is intended for the Mobility Service (Mcx).

When you enable Internet Information Services (IIS) request tracing for the Lync Server Mobility Service (Mcx), the log files that are generated can consume up to three gigabytes of disk space per day. IIS trace logging is enabled by default. You should monitor the Front End Servers to make sure that they do not run out of disk space.

By default, IIS stores the log files at %SystemDrive%\inetpub\logs\LogFiles.

To turn off IIS request tracing for an entire server, at the command line, type the following:

Copy Code
%SystemDrive%\Windows\System32\inetsrv\appcmd set config /section:httpLogging /dontLog:True
