I am having problems using Scripting.FileSystemObject
from VBScript (ASP) on an XP Professional machine?

Everything is fine until I try to use GetFile(),
CreateTextFile(), or OpenTextFile() - then the page never
loads (no error is shown). What's more, after unloading
the ASP application from IIS, I can no longer access the
Application properties and have to reboot my machine to
access any ASP pages. This same script runs fine under
Win2K.

Is this a known bug, is it being dealt with, is there a
patch, or does anybody know a workaround???
