Proxy Server Logging Fix: Msplog.dll Changed to Record 4 Digit Year

By Default, Microsoft Proxy Server 2.0 logs the year in two-digit format.

This is by design and does not affect the year 2000 compliance of Microsoft Proxy Server 2.0

This problem is resolved in Microsoft Proxy Server 2.0 Service Pack 1 (SP1). For more information about Service Pack 1, please see the following article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in Microsoft Proxy Server 2.0.

This fix was created to optionally allow Proxy Server to log four-digit years. To obtain this fix, contact Microsoft Product Support and reference this Knowledge Base Article.

Msplog.dll has been fixed to read a format string from the registry to be used by the date format API (GetDateFormat). Both the format string and the date field string are limited to 15 characters. Using a format string that is longer than 15 characters will cause the logger to use the current format (M/D/YY).

If the date string returned by Windows NT is greater than 15 characters, the entire log entry containing this date string will be thrown out and not logged to the file. In addition to the hotfix, the following registry entry must be changed:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

1. Start Registry Editor (Regedt32.exe).
2. Locate the following key in the registry:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ W3Proxy\Parameters\
   NOTE: The above registry key is one path; it has been wrapped for readability.
3. On the Edit menu, click Add Value, and then add the following registry value:
   Value Name: LogFileDateFormat
   
   Data Type: REG_SZ
   
   Value: Date format String (See below for samples.)
4. Quit Registry Editor.

The following date format string samples use March 4th 1999 as an example: NOTES

• This registry change is common to all Proxy Server logging configurations.
• The registry key is accessed once during the creation of a new log file.
• Changes to the key's value will reflect after restarting the services.
