ISAPI properties reference

When you install the Multicast and Advertisement Logging Agent, Windows Media Services creates the following registry keys in the registry of the computer. You can use these registry keys to modify the properties of the Wmsiislog.dll application extension. The following table provides information about the property values, which are stored in the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media\Server\ISAPI\Logging.

Setting	Type	Description
LogDirPath	REG_EXPAND_SZ	Provides the path to the log file. By default this value is %systemroot%\System32\LogFiles\WMS_ISAPI.
FreeSpaceQuota	REG_DWORD	Provides the minimum amount of available disk space on the drive to which log files are being written. If the amount of free disk space is not available, the log file will not be written and the multicast logging application will stop.
UseLocalTime	REG_DWORD	Determines the time zone (local or Coordinated Universal Time) to use. A nonzero value indicates that local time is used.
UseUnicode characters (UTF-8)	REG_DWORD	Specifies whether the log file should contain Unicode or ANSI text. A nonzero value indicates that Unicode (UTF-8) is used.

Caution

Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

Note Image Notes

If you move Wmsiislog.dll to another Web server for logging, you must manually register it on the server by typing regsvr32 wmsiislog.dll at the command prompt. If this application is used on a Web server without being registered, it will use the default values.
If you change the default logging directory, you must grant the Multicast and Advertisement Logging Agent permissions to write to that directory. For the statistics to be successfully written to the log file, grant read, write, and modify permissions to the Network Service account and IWAM_HOSTNAME.
