Take the loopback address out of the HOSTS file located in your Windows\i386 directory. That'll be a start. Run the above mentioned tool. Then look into getting the cwshreder & shootthemessenger from
www.grc.com and run them both.

Run a search for "hosts" on your main harddrive and open that file in notepad. Remove all instances of "127.0.0.1" from the list. You could remove everything from the file too. Save the file to its original location and overwrite the old file.
Here's a concatination of my HOSTS file.
---------------------------------START
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
