Deleting DSN Caching

[Tagge]

Hey folks,

I run a small network with several computers connected on
and off site to the network. Using DNS I've named several
commonly used network resources on our network, as to
make them for freely changable for any unforseen
occurance (HW failure etc).

However, after changing the DNS to point to different IP
addresses on my network this last time, it seems that all
PCs off site which dial up to the main offices have lost
the ability to resolve our DNS properly and get to the
new address of the mail server. Instead they time out and
fail to connect.

Is there a setting in Windows, or a place, where I can
wipe out the DNS cache on individual PCs? Because I've
been able to repair one PC by accidentially refreshing
that cache, however I haven't had success in replicating
those events on other machines. Help would be appreciated.

T,

Try "ipconfig /flushdns" from a command window.

Paranoia comes from experience - and is not necessarily a bad thing.

Hi -

On XP Professional machines you can disable the DNS
Client service as long as the machines aren't members if
a Win2k or Win2k3 domain. This should solve your problem.

Good luck -
