ASP Fails with Requested Header Not Found Error Message
This article was previously published under Q170044
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:
After you install Active Server Pages (ASP) and try to run one
of the sample pages using Anonymous Authentication, you will get
following error message:
Requested Header Not Found is returned.
NOTE: This error is a permission issue and can be returned
under other circumstances. Any time a secured page or directory
is accessed and the only authentication method enabled under
Internet Service Manager is Anonymous, the above error message will
be returned to the browser.
- Go to the WWW Service properties and disable Anonymous Access.
- Enable Basic Authentication only.
- Try to select one of the sample ASPs with the browser.
- When you are presented with the credentials dialogue box, log in
using a valid administrator's account.
- If the page loads sucessfully, you have a permissions problem.
To correct this problem, grant your Anonymous User
(IUSR_machine-name by default), the following permissions to the
following directories:
NOTE: When you apply these permissions, only apply them to all
existing files unless otherwise noted.
- Grant IUSR Read permission to the root directory of the drive
that ASP is installed on.
- Grant IUSR Write permission to the Microsoft Windows NT Server
directory.
- Grant IUSR Read permission to the System32 directory.
- Grant IUSR Read & Execute permission to the System directory.
- Grant IUSR Read & Execute permission to the Inetserv directory.
- Grant IUSR Read permission to the InetPub directory.
(By default, the next two directories are located in Program
Files, Common Files, System.)
- Grant IUSR Read permission to the OLE DB directory.
- Grant IUSR Read permission to the ADO directory.
After you apply the above permissions:
- Change the authentication method in Internet Services Manager
to disallow Basic Authentication and enable Anonymous Access.
- Close and restart your browser in order to refresh its cache.
- Try to run a sample ASP with the browser.
APPLIES TO
- Microsoft Internet Information Server 3.0
- Microsoft Active Server Pages 1.0

didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each

edits), please consult a professional.
