XWEB: Active Server Components Not Compatible with IIS 4.0

• Microsoft Exchange Server, version 5.0
• Microsoft Exchange Active Server Components, version 5.0

SYMPTOMS

You may experience either of the following symptoms:

• When you are logging on to a Microsoft Exchange Server computer using the Microsoft Outlook Web Access (OWA) client, you may receive the following error message:
  
  

  HTTP Error 401 401.1 Unauthorized: Logon Failed.




• While attempting to install the Active Server Components shipped with Microsoft Exchange Server version 5.0 on a computer running Internet Information Server (IIS) version 4.0, you may receive one of the following error messages:
  
  

  To install the Active Server Components you need to have previously
  installed Windows NT 4.0, Internet Information Server (IIS) and
  Active Server Pages. Microsoft Exchange Server Setup
  ID no: c1032b99

  Or
  
  

  The Active Server Components failed to install properly.

  If you click OK after receiving the second error message, you receive the following additional error message:
  
  

  The system cannot find the file specified.
  Microsoft Windows NT
  ID no: 0xc0020002

CAUSE

Internet Information Server (IIS) version 4.0 has been installed and configured to access the computer running Exchange Server 5.0. IIS 4.0 is not supported by the Exchange Server version 5.0 Active Server Components. IIS 4.0 is supported by Exchange Server version 5.5.

WORKAROUND

To work around this problem, install Microsoft Exchange Server 5.5 before installing IIS 4.0 in order to use it with the OWA client.

Note that you may also be able to work around this problem by uninstalling IIS 4.0, and then installing IIS 3.0, before you install the Active Server Components. After you install the Active Server Components, you can reinstall IIS 4.0.
