Turning it off reduced the frequent XP pauses I was getting, with no
perceptible down-side. Coming back to the original question, since our
systems seem to work well without it, what benefit does it provide?
DHCP Client service also seems to offer no benefit on my system - would also
like a view on the benefits or otherwise of that service.
Don't worry. I got your post, understood it just fine, and the others need
to go find the whole thread instead of sidetracking you with comments that
have nothing to do with the topic.
However, I have turned off the DNS service (put it on Disable) and my
internet still works fine. Are you telling me that on your computer if you
disable this service, your internet browsing stops?

DNS is a necessary service. It is how IE and anything else you use

www.yahoo.com in your browser

would be unable to find it (you would have to actually put in the
ip
address). Hope this answers your question.
As you didn't quote the post you were replying to, we don't know what
the
question WAS.
I was replying to the original question which is what i thought the
topic was about. I am new to this board but not new to posting.
Thanks for the info i will quote going forward.

The only evidence I can find that disabling DNS in xp speeds up the
perfomance is a valid one but it does not totally disable it. Please
read below my post for this example. As far as DHCP there are so many
different home/office settings that it is difficult to detail the
benefits/downside of leaving it enabled. If you wanted to describe
your specific connection maybe I could detail what might be right for
you. One certainty I have learned from Microsoft products is there are
101 different ways of doing something usually with the same end
result. My recommendation is to leave the xp services as they are in
a default install. There are exceptions to the rule but I do not
think the benefits are that great. Thanks for listening to my long
Rant LOL
By default, Windows XP will cache the IP addresses connected to DNS
names (such as website addresses) as they are entered into your
browser. This speeds up subsequent visits to the same addresses
because the system does not have to search for the IP address that
the DNS name represents.
This is good for Internet performance as a whole, but it does have a
downside. If you type in a valid URL that is not functioning at that
point in time, Windows will cache the unsuccessful result, meaning
that all attempts to access that address may fail until the failed
entry is gone from the cache. This takes about 5 minutes.
You can prevent Windows XP from caching unsuccessful DNS lookups by
creating three new registry values.
To do this open REGEDIT and navigate to:
'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters'
Create the following DWORD values:
NegativeCacheTime= 0
NetFailureCacheTime= 0
NegativeSOACacheTime= 0
Reboot for the changes to take effect.
