Question

I deployed my website on IIS 7, it’s no error while I compiled it, however when deploy the application on remote IIS 7, to check the page, the index page is fine, but the error message show at following pages.

the problem is, when user starts to search information (which is a xml file request), the page show some error like:

Server Error in '/' Application.

I am wondering if it’s a problem for IIS 7 settings, but till now I can’t fixed it. My server environment is .NET 4.0 and IIS 7, on windows 7.

I have no idea how to trace this error, if there are more information or code need to be offering, please remind me, and thanks for your answering.

Answer 1

By the looks of the stack trace, you’re passing a URL to the XmlDocument.Load function. If the file is located on the local server and the executing application pool has access to the folder, try using Server.MapPath (docs) to get the file system location and pass that in to the XmlDocument.Load instead.

If passing a URL is the desired behaviour, check that the application can actually access the external resource (proxy settings on server etc.).
