I created a subdomain called adserver

I tried to execute a script or any html file it keep saying HTTP 404 - File not found

http://adserver.e-zbanner.com/cgi-bin/index.html

I created a subdirectory test and upload a index.html file and it worked fine. Anything at the root works fine too.

Any ideas?

You're getting a 404 error, which means the URL you typed isn't finding anything. What did you set as the document root for the subdomain? Did you add a ScriptAlias for your CGI directory for the subdomain?

You'd get more useful responses if you let us know:

- What webserver are you using (eg, Apache)?
- Did you set this up manually, or via some sort of control panel?

I'm sure someone can help a bit more with this information.
