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:

SYMPTOMS

When upgrading to Internet Information Server (IIS) 4.0, Perl script mappings, which are case sensitive, are converted to uppercase.

Specifically, the "%s" string is converted to "%S" UPPERCASE (without the quotation marks).

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

To work around this problem, change the "%S" text back to "%s" (without the quotation marks). To do this, perform the following steps:

In the Microsoft Management Console, right-click your Internet Information Server name and click Properties on the shortcut menu.
In the Properties dialog box, click the Edit button next to Master Properties.
In the Application Settings section of the Home Directory tab, click Configuration.
Double-click the entry for the extension .PL to edit the Perl mapping.
In the Executable box, you will see a path followed by "%S %S" (note that %S is uppercase). For example, you will see something similar to:
```
      C:\perl\bin\perl.exe %S %S
  
						
```
Change %S %S to lowercase %s %s and then click OK.

STATUS

Microsoft has confirmed this to be a problem in Internet Information Server version 4.0. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
