I read somewhere that...
The default time period for keeping an address in the cache is 24 hours.
After a little experimenting I have found out why ipconfig /flushdns isn't
working for you.
ipconfig /displaydns and ipconfig /flushdns do *not* work with the DNS
Client service *not* running.
You have to have the DNS Client service running in order for
ipconfig /displaydns and ipconfig /flushdns to work properly.

Wes,
Apparently I'm typing everything in correctly and it's making an attempt
to flush the dns cache. The error I get reads:
Windows IP Configuration
Could not flush the DNS Resolver Cache: Function failed during execution.
Are there any automatic flushes that occur under normal operation?
Perhaps this flush failure is how the file size got out of hand... ?
Thoughts? Other things to try?

John,
Jeepers! 2.4MB I thought my HOSTS file was pretty good sized at 288 KB.
It is ipconfig.exe and it is available on XP Home.
The /? switch will show Help. I.e. ipconfig /?
Type or paste ipconfig /? in a command prompt window and see if that
works.

Wesley,
Thank you very much for your response. I tried the "ipconfig /flushdns"
and the "ipconfig /displaydns" commands. Unfortunately both "failed
during execution". Are these available for the XP Home edition or only
XP Pro? At any rate, the editor's note about running services.msc and
setting the service startup to "manual" solved the problem. Many thanks
for taking the time to help!!

You can purge the DNS Resolver cache.
The ipconfig /flushdns command provides you with a means to flush and
reset the contents of the DNS client resolver cache. Resetting the
cache does not eliminate entries that are preloaded from the local
Hosts file. To eliminate those entries from the cache, remove them
from the HOSTS file.
Open a command prompt...
Start | Run | Type: cmd | Click OK |
Type or paste this in the command prompt window:
ipconfig /flushdns
Hit your Enter key.
You can then view the DNS cache.
Type or paste this in the command prompt window:
ipconfig /displaydns
Hit your Enter key.

[[ Editors Note: in most cases a large HOSTS file (over 135 kb) tends
to slow down the machine. This only occurs in W2000 and XP. Windows 98
and ME are not affected.
To resolve this issue (manually) open the "Services Editor"
Start | Run (type) "services.msc" (no quotes)
Scroll down to "DNS Client", Right-click and select: Properties
Click the drop-down arrow for "Startup type"
Select: Manual, click Apply\Ok and restart.
You can see that the above "Service" is not needed (after a little
browsing) by opening the Services Editor again, scroll down to DNS
Client and check the "Status" column. It should be blank, if it was
needed it would show "Started" in that column. ]]

So I startup my computer and it works at a staggeringly slow pace.
Using Process Explorer I've found that an instance of svchost.exe with
only the Dnscache service is consuming my CPU. If I kill the process
then the problem goes away. However, this seems to make other apps
like Explorer do funny things, like take me off line constantly.
Also, Dnscache (a Microsoft product) seems to be an important
component of a healthy, internet-connected Windows XP. Anyone know
how I can repair the Dnscache service?
