IIS settings - Error pages

[FN-GM]

Hi,

Does anyone know of a good guide or tips to get error pages working in iis7 please?

These should show you how to go about setting up custom pages:
IIS7 ? Enabling Custom Error Pages - rakkimk : The Official Microsoft IIS Site
How to configure IIS7

If that does not work you can specify them in the web.config file like this:
Prabir's Blog | Custom Error for non ASP.NET files
http://www.asp.net/learn/hosting/tutorial-11-cs.aspx

and this tels you how to turn on failure tracing which is also quite useful:
