I want to open a port in my XP's firewall for file
sharing with Limewire. When I get into the advanced
settings and then go to sevice settings, I type in the IP
address 127.0.0.1 and the other information then hit OK.
I exit then re-enter to see if it has changed and it
reverts to YOUR-LK4RLMSU41 every time. I tried different
IP addresses, but it only reverts back to YOUR-LK4RLMSU41
when I put in 127.0.0.1 -- and that's the only one I need!

Any suggestions?

Seems as if the 127.0.0.1 address has an entry in your hosts file with that
name.
Check the hosts file and see if that is the case.
You can do a search for hosts or access the file directly at
c:\windows\system32\drivers\etc\hosts

I have been having the same problem and 127.0.0.1 comes up often. I am using XP Pro but am a standalone PC connecting to ISP but no corp network. I am currently in dialup, no Lan or broadband. Virus protection with McAfee up-to-date, use McAfee Firewall and have applied all lasted patches for virus and worms. Yet sometimes in Outlook Express my pop3 server name is changed (not by me) from pop.earthlink.net to 127.0.0.0. I also continue to receive a large amount of porn and other unwanted emails and many have source as HELO localhost 127.0.0.1.
In C:\Windows\system32\Drivers\etc there is a file Hosts. Properties say just File, no extention, etc. When I open it it has the following
.
#This is a sample HOSTS file used by Microsoft TCP/IP for Window
# This file contains the mappings of IP addresses to host names. Eac
# entry should be kept on an individual line. The IP address shoul
# 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 on
# space

# Additionally, comments (such as these) may be inserted on individua
# lines or following the machine name denoted by a '#' symbol

# For example

# 102.54.94.97 rhino.acme.com # source serve
# 38.25.63.10 x.acme.com # x client hos

127.0.0.1 localhos

Should I edit this file and remove 127.0.0.1

thank

You seem to have posted without linking to the message to which you refer.
So, I do not know what is your "same problem as"
however, your hosts file is standard issue and should be left as it is.
The localhost 127.0.0.1 is the loopback address used by all machines
that use Tcp/Ip and this entry in the hosts file just gives it a friendly
name

The 127.0.0.1 in your HOSTS file is normal and refers to your LOCALHOST
loopback address. Leave it alone.

HELO localhost 127.0.0.1? Are you running a mail server on your system?
Another possibility is HotPop or YahooPopper which retrieve Hotmail and
Yahoo emails like a POP3 account to your email client (OE in this case).
For OE to access Yahoo or Hotmail through HotPop or YahooPopper, your mail
client accesses these programs through the LOCALHOST address . . . or
127.0.0.1.

127.0.0.1 is the IP address reserved for "self".

Is YOUR-LK4RLMSU41 the name of your PC?

Routing things to 127.0.0.1 is an often-used way of getting rid of
call-home behaviour, and is also used by software toi "trap" things
that would otherwise go "outside". For example, an antivirus may
patch itself into the email flow by taking over the process of
downloading mail, then having the email program get it from itself on
"POP3 server 127.0.0.1". For another example, malware may hijack
antivirus URLs to 127.0.0.1 to foil updates or sample uploads.
