Internal Server Error (500) in Upload File method

[Pedro Carvalho]

I am using a WebClient.Upload File method on the Client side and, to accept
posted files on the Server side, I am using an ASP.NET page with the
following code:

void Page_Load(object sender, EventArgs e)
{
foreach(string f in Request.Files.AllKeys)
{
HttpPostedFile file = Request.Files[f];
file.SaveAs("c:\\WUTemp\\" + file.FileName);
}
}

When Client and Server side are on the same machine (localhost/127.0.0.1)
everything runs ok but when using a different server and call it from the
WebClient.UploadFile method:

WebClient.UploadFile("http://srv1/ASPPostFile/Upld.aspx","POST",fileToUpload),
it returns the error: "(500) Internal Server Error". I've already tried to
solve this problem with all the instructions I found in Microsoft and MSDN
but with no results.
Is there any way to have a more detailed error when using 'catch
(System.Exception ex)' ?
I have no idea what to try now and I would appreciate if someone could help
me to follow in the right direction.
Thanks for your help

Today i've been looking also to 'www.aspfaq.com' and tried all their
instructions without any positive result.
I'm trying to solve this for some days now and I don't know what else to do...
Thanks for any help.
