Hi! You should be able to code a custom error message using one of the
scripting languages (VBScript, JScript) that would prompt for
authentication. I haven't done this, but I don't see any reason why it
could not be done.

Hi
Thanks. This is sort of what I am wanting, but instead of returning an error
saying that you are not allowed access I want it to prompt for basic
user id and password if the ip doesn't match. ie. if a user requests
a page and their ip matches they automatically get it no questions
asked. If their ip doesn't match then they get prompted for userid
and password. If their user id and password fail then they get the
access denied message. Do you know if this is possible?
Thanks
Regards
Glen

You can restrict by IP address on IIS 4.0 only by logical server. You
cannot limit by IP address on a directory-by-directory or file-by-file
basis. However, IIS includes the capability to run "virtual servers," which
allows several sites to run on the same physical server, using different IP
addresses or port numbers. This provides a workaround to the problem, since
each of the virtual servers can be configured with its own set of IP address
restrictions. If you have a spare IP address (or want to instruct users to
specify a nonstandard port), you can add a virtual server with the root
pointing to the "secure" subdirectory.
The security configuration is fairly easy to set up. Both settings are
under the "Directory Security" property tab. "IP address and domain
restrictions" allows you to restrict the site by IP address/domain name.
"Anonymous access and authentication control" allows you to disable
anonymous access and enable either unencrypted (Basic) or encrypted (Windows
NT Challenge/Response) authentication. Challenge/Response only works from
IE browsers 3.0 and higher. Authentication is based on the built-in Windows
NT security, so you will have to set up user account(s) and assign
permissions to the files and directories you need to limit access to.
Hope that helps!

I go to the bother of downloading and installing it.
