OpenTextFile Method Not Working

I am trying to open a text file to read the contents using the following code:

Dim objFSO, objFile
Const ForReading = 1, ForWriting = 2, ForAppending = 8

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile("c:inetpubwwwrootDemoAppscontenido.txt",ForReading)

The problem is that the execution stalls at the OpenTextFile method and stays there until the script timeout error. The FileSystemObject is correctly created because I have been able to create a drive object and display the volume name, but actually trying to read or create (with the CreateTextFile method) a file is not working

I am using IIS 5.0 running on Win 2k Pro
