Win2008

I moved a site onto a 2008 box after having it on a 2003 server box and did some testing only to find that the redirection on an error failed to go to the error.aspx page I had. I've been googling this for quite some time to no solution.

I looked for an IIS forum, but couldn't find one. I think the solution is in IIS, but I'm not sure.

Any help would be much appreciated.

So, you are redirecting on Error Page from global.asax ? Can you show us the code for Application_Error Secction ?
I guess you are using Response.Redirect From Application_Error.

This is the Problem related with IIS 7 and Its integration mode. Which mode you are using ? Integrated or Classic ?
if Its Integrated mode and change to classic it may work.
Here[^] I found a good solution [ The summary as below ]

Analysis :
The problem is caused by changed behavior of IIS7 new integrated pipeline mode when calling Response.Redirect() in Application_Error. The default .net error page will be rendered before the actual redirection occurs due to error is detected.

Solution

1. Remove the module definition of ScriptModule under system.webServer/modules in web.config. e.g:

<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Remove Application_PreSendRequestHeader and Application_PreSendRequestContent event handlers from global.asax if they are not used.

2.Call Context.ClearError or Server.ClearError to clear the error before using Response.Redirect() in Application_Error.

Hope this will help you :-D
