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

To determine whether you have the domestic or international version of Internet Information Server (IIS), you can view the version information of the Secure Sockets Layer (SSL) security provider file.

MORE INFORMATION

The domestic versions of IIS provide a higher level of data encryption than the international versions and are restricted from export. In IIS 1.0, the SSL provider file is Sslsspi.dll; in IIS 2.0 it is the Schannel.dll file. These files are located in the %Systemroot%\System32 directory.

To view the version information under Windows NT 3.51:

Open File Manager.
Select the appropriate .dll file in File Manager.
Press ALT+ENTER.
Select File Information.

To View the version information under Windows NT 4.0:

Right-click the appropriate .dll file.
Click Properties.
Select Version.

The domestic version will read SSL Security Provider (Domestic Use Only); the international version simply reads "SSL Security Provider."
