HTTP 404 file not found error

Hi! All the IIS Pros,

I am having a strange problem. I have certain ASP pages that are well tested and working in many places. But there is one server (windows 2000) on which some of the asp pages do not work. I get a HTTP 404 file not found error. I checked more than a few times and made sure the files are there on the server where the IIS application is looking at. The strange thing is, some of the ASP pages are working fine. Only those ASP pages whose name starting with 'ETC' is not working. If I change the name of the same ASP to some thing other than "ETC" it works fine.

Do you think there is some software on the sever that tells IIS to block requests coming from any ASP pages starting with the name 'ETC'? Is there any way I can find out what is going on.

Any input is greatly appreciated.
Thanks,
GT

I've never heard of a problem like this, but you can do most anything with custom isapi filters.

Doug, Thanks for the reply.

Is there any way I can find out if any custom isapi filters are set up on the web server? Does the details of custom filters reside in IIS or in the registry?

Thank You.

You could look at the mappings in the IIS management console, I guess. I am not an expert in this. Some server apps may install custom filters, but it's probably not a likely cause of your problem. Can you get any more information from the error page about where the server is trying to look for the page that's not found?
