Custom 404 not found page in iis 7 for Classic ASP

I installed windows 2008 server integrated iis 7.0

1 day ago, i use windows 2003 and iis 6.0

with windows 2008 server, everything is alright except one thing.

in 2003-iis6 i could use custom 404 pages to handle for url friendly sites. example i could set custom404.asp as custom 404 pages(execute url)

in 2008, i can't do it. when i set custom 404 page a开发者_如何学Cs /custom404.asp, nothing happens. in custom error pages it says this is for asp.net

how can i do it?

On the "Error Pages" section in IIS manager select the "Edit Feature Settings..." under the Actions section. Ensure that "Custom error pages" is selected.

the webconfig file below fixed the problem. i share in case anyone needs

save the code as web.config and move it to main site folder
