ASP Error and IIS 7.0

Question

In IIS 6 ASP errors were displayed with the line number and a description of the problem. For example,

{call dbo.spGetCommunityInfo(xx)} 
Microsoft SQL Native Client error '80020005' 
Invalid character value for cast specification 
/communitydetail.asp, line 42

IIS 7 changes the way ASP errors are handled and displays something a lot less helpful. For example,

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request

Does anyone know what configuration changes are required to get the behavior of IIS 6 in IIS 7?

Answer 1

You can use AppCmd to turn on ScriptErrorSentToBrowser (it's false in IIS7 defaults, it was true in IIS6). AppCmd live in %SystemRoot%\system32\inetsrv and you need to run it as admin:

appcmd.exe set config -section:system.webServer/asp -ScriptErrorSentToBrowser:true
