Windows 98 SE does not provide support for manually flushing the DNS
cache. This capability is inherent to the NT-based operating systems
such as Windows 2000 and XP (the 'ipconfig /flushdns' command you may
be familiar with). In Windows 98 SE, the only simple manual method to
flushing the DNS cache is to perform a reboot (shut down the computer
completely, then restart it).

In Windows 98 SE, the DNS cache uses a timeout setting stored in the
Registry to determine whether it is necessary to reconfirm an address
resolution. If you refer to the following Microsoft Knowledge Base
Article, 263558, you will learn more about this:;en-us;263558

From this article, you will see that, prior to Internet Explorer 4.0,
the DNS cache timeout was set to 24 hours. From IE4.0 onwards, this
value should now be automatically set to 30 minutes (ie. 1800

If you are adventurous enough to play around in your system's
Registry, you can achieve a DNS cache flush by setting this Registry
setting to a very low value, such as 1 (for 1 second). Start up
Internet Explorer, and enter the URL that you want to get to. This
will cause a new query to be made for the DNS entry of the domain in
question. Then, set the Registry value back to a higher value such as
1800. Please note that you do not want to have the DNS cache timeout
set too low on a normal basis, as this will slow down your online
experience due to the constant requests for DNS resolution that your
PC will need to make.

To summarize, you can flush your DNS cache in Windows 98 SE by
rebooting, or by playing around with the Registry settings using the
information in the MS KB Article linked above.

Hope this helps!
