Re: Secondary DNS and PIX

I have considered this option too, but with a production company of this many
people who depend on the network connection, I am weary of doing something
like this. I have had CISCO examine the configuration several times, but you
are right that it could still be a configuration. I have considered another
hardware firewall and may have to do that but only as a last resort.

For now, I know that my DNS is overburdened and needs some relief.
Thanks for the suggestion

I replaced and updated the pix with the latest OS and patches and installed
on the network and I still have the same problem with the pix locking up.
But in my troubleshooting I noticed that my DNS counters for "total query
received" and "total responses sent" were maxed out at 100. My questions are
as follows:

1.) any idea what the counter should look like for an SBS DC that is
running DNS that has about 70 clients on it?

2.) How can I add a secondary DNS server to the SBS network, and how to I
configure it to offload some of the DNS burden from the DC? I currently have
2 additional W2K3 machines that I could configure for DNS.

Thanks for the information, assistance and options in advance.

maybe something in the pix is not configured correctly despite being
patched and updated. have you tried using a different firewall by chance?

find an old desktop, put an extra nic in it and install smoothwall
(simple, open source network firewall / smoothwall.org). run it for a
few days and see if it you still have these same issues.

you can even setup a proxy on it to relieve your SBS of repeated DNS
requests.
