I should be interested to know what manual told you to declare a hard path beginning by "C:\Documents and Settings" in your web.config in ASP.Net.
What I understand of Millenia's intervention is : please explicit line number 75 of web.config, so that we can see what is missing.
And also, to verify the file that is mentioned there, open your windows explorer and have a look at that path.
And do not forget that the web browser where your page appears in, is not supposed to run on the same machine as the server.
