Sorry for the cross post. I posted this in web services general, but after
thinking about it, I think it will get more hits here in asp.net web
services. I'm on Windows XP Pro running a web service on my local pc (which
will eventually be moved up to a server). I need to access several files on
my local hard drive (ultimately the server's hard drive) from the web
service. I'm running into a file access problem with this. To illustrate my
problem, I've got it really stripped down. Here is a web service in c# ...

using System.IO;
...
[WebMethod]
public string OpenFile()
{
  string retVal = "OK";
  try
  {
     FileStream fs = new FileStream("c:\\hello.txt", FileMode.Open);
  }
  catch ( Exception e )
  {
     retVal = e.Message;
  }
  return retVal;
}

When I browse to this service in IE and Invoke the OpenFile method, my
return value is "Access to the path "c:\hello.txt" is denied."

I've tried changing my IUSR_BRANDON user to be a member of the Administrator
group. I've changed the anonymous access user to Administrator. Let IIS
control password as well as type it in explicitly. I've fooled around with
several things, but nothing I change or flip seems to have any effect.

This should be pretty easy shouldn't it? I mean, the asp.net process should
be able to see the local drive right? Any help will be greatly appreciated.
I'm beating my head on the keyboard here.

Thanks is advance,
