Windows XP is ignoring my changes to hosts file

I am having a problem where no matter what I do Windows completely ignores
any additions to my hosts file.

I tried adding the following entry:
127.0.0.1 something
to my hosts file, and then I open up a new command prompt and type "ping
something" and after a few seconds delay it says ping request could not find
host something.

I have tried the following:

1. Made sure the file is just "hosts" with no file extension like .txt or
anything. 100% sure about this

2. Opened up regedit and navigated to the Tcpip parameters looking for
DatabasePath and made sure it pointed to system32/drivers/etc.

3. I have run ipconfig /flushdns numerous times

4. I have rebooted numerous times

5. I erased everything in my hosts file except for the one default entry
"127.0.0.1 localhost" and my new entry underneath it in a new line. So
the file only contained those two lines. the ip number and the hostname were
separated by 5 spaces. I also tried using tabs.

Other than that this is a brand new build of Windows XP Pro on a formatted
hard drive and I barely even installed anything on it besides my development
tools like Eclipse and Java JDK. There is absolutely no funny business with
my network, it is setup to use my wired LAN no proxies, auto detect DHCP
settings, just about everything is default!

Please help! This is such an odd problem

Many security programs now provide "Locks" against changes to
the Hosts file. Would you have anything installed that might interfere
with Hosts resolution ?

The NSLookup command might help, I'd read through the following:

One or more options/settings in an ever-growing number of third-party
applications may be disallowing the change(s) from "sticking". These include
but are not limited to Ad-aware's Ad-Watch, Spybot Tea Timer,
SpywareBlaster, SpySweeper, Spyware Doctor, Norton AntiVirus, McAfee
VirusScan and/or Antispyware, and Zone Alarm (Free and Pro).

Here's something else about NAV that you may not be aware of:

Well, if my changes were not "sticking" due to a third party program, then
when I opened the hosts file again it should show the original file, not my
changes, correct? And whenever I open my hosts file even after a reboot I see
my changes in place.

Also, I have not installed any of those programs or any kind of anti virus
or anything like that. Just a few development tools and that's it.

I'm reading up on the NSloolup command now

nslookup contacts the dns server directly. So whatever entries you have
in the hostfile won't show up when using this tool

Yeah so it looks like it won't help me.

Any other ideas? I'm willing to try anything at this point. It is such a
bizarre situation.

Disable the DNS Client service (or just stop it and change it's Startup Type
to Manual). This is a solution I stumbled across quite some time ago when I
ran into the same problem as you. I've yet to come across an explaination
as to why all of a sudden XP starts to ignore the hosts file. This solution
could possibly cause problems, depending on your environment (as far as I
can tell it's only necessary if you're in a domain setting), but it has yet
to cause me any problems.

Yes! That did it. I don't think I rely on tha DNS client service for anything
so it shouldn't affect me either.

Sure is strange though how this was required for my latest build on my
laptop. After formatting and installing Windows XP on this laptop several
times over the past 4 years it only decided to this this one time. .. oh well!

Thanks!

Your welcome. Glad it worked.
