authentication with iis4

[Glen Davies]

Hi

Does anybody know if the following user authentication scheme is 
possible with iis4. I want to have  subdirectory of the server for 
which the server first of all checks the client ip, if the ip is valid access is 
allowed, if not the client is asked for basic userid and password. 

It is a bit hard to tell from the online documentation. It is obvious that 
it does one or the other but it is not clear if two levels of 
authentication are possible. I want to find out if this is possible 
before I go to the bother of downloading and installing it.

Thanks
Regards
Glen
