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.

   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 behavior, to use the Microsoft Exchange Server, version 5.0
Active Server Components on the computer that runs IIS, you must perform the
following steps:

1. Remove IIS 4.0.

2. Install IIS 3.0.

3. Run the Microsoft Exchange Server, version 5.0, Setup program and install the
   Active Server Components.

4. Install IIS 4.0 to upgrade the computer.

Another option is to run the Microsoft Exchange Server, version 5.5, Setup
program and install the Outlook Web Access components on the IIS 4.0 server.
