We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SUMMARY
You can use three different logging file methods with Internet Information Server (IIS). These methods are Daily, Weekly, and Monthly. You can select these methods by selecting the appropriate service computer name in Internet Service Manager. Then select Properties, Service Properties, then the Logging tab.

The Daily log files are created at 12:00 A.M. of each day. They use the following date format for filenames: INyymmdd.log.

The Weekly log files are created at 12:00 A.M. on Sunday of each week. They use the following date format for filenames: INyymmww.log.

The Monthly log files are created at 12:00 A.M. on the first day of each month. They use the following date format for filenames: INyymm.log.



MORE INFORMATION
When you switch from Daily to Weekly logging formats, a new Weekly log file is created at the time the change is applied, then again at 12:00 A.M. on Sunday of each week.

For example, on Friday afternoon the change is made from Daily to Weekly format. A new Weekly log file is created at this time, then again at 12:00 A.M. the following Sunday.

When you switch from Daily or Weekly to Monthly logging formats, a new Monthly log file is created at the time the change is applied, then again at 12:00 A.M. on the first day of the next month.

For example, on Friday afternoon the change is made from Daily to Monthly format. A new Weekly log file is created at this time, then again at 12:00 A.M. the first day of the following month.
