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.

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

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:
- Remove IIS 4.0.
- Install IIS 3.0.
- Run the Microsoft Exchange Server, version 5.0, Setup program and install the Active Server Components.
- 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.
