Centralized Binary Logging in IIS 6.0 (IIS 6.0)
Centralized binary logging is the process by which multiple Web sites write binary, unformatted log data to a single log file. When enabled, all Web sites on your server write log data to a single log file.
You must be a member of the Administrators group on the local computer to run scripts and executables. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run your script or executable as an administrator. At a command prompt, type runas /profile /user:MyComputer\Administrator cmd to open a command window with administrator rights and then type cscript.exeScriptName (include the script's full path and any parameters).
To enable centralized binary logging for all Web sites on your server running IIS
From the command prompt, type net start W3SVC, and press ENTER. The WWW service starts and centralized binary logging is enabled.
The binary log file is created in the W3SVC folder located at systemroot\System32\LogFiles\.
