problems with authenication in C#

[kj96]

I have a intranet page that I want to use to open a certain file from a
network location make changes to it and then write the changed file
back to the same network location

<my try at the code>

TextReader tr = new StreamReader("\\\\server\\location\\text1.txt");

StreamWriter tw = new StreamWriter("\\\\server\\location\\text2.txt");
</my try at the code>

I have setup IIS to use a domain user account that has read and write
rights to the server location.

I get the following error.
********************************************************************************

Server Error in '/web' Application.

Hi there... which user is being authenticated (IUSR_MACHINENAME) ? Remember
that it belongs to the Guests user group. The same privileges as user but
with more restrictions. Does the user being authenticated have access to
that folder (Security)? Does the user being authenticated have the
corresponding checkboxes selected in your case read/write attributes?
Check those things out first and try again...

Regards,
