DNS not responding

[Steve Grosz]

I am running DNS on a W2k Server with a DSL connection.
It seems that DNS shuts down after a while, at random
periods throughout the day, and I'll get this info in the
browser page when trying to get to pages I'm hosting:

Problem Report
The system detected a DNS Server Failure while
attempting to resolve the host specified in the requested
URL.

Message ID
DNS_SERVER_FAILURE

Problem Description
DNS server failure encountered.

Possible Problem Cause
The DNS server is temporarily unavailable, or the
network is experiencing transient data loss.

Possible Solution
Try again at a later time.


What could be causing this to stop? I've checked the
event logs, and it doesn't give any indication that
anything is wrong. I have to physically restart my
machine to get it to come back up (or have someone do it
for me if I'm not there)

Any help would be appreciated, this is getting very
frustrating!!!

Are you sharing this internet connection with ICS or NAT?
Don't use ICS at all and don't use NAT with the DNS proxy enabled.

Post back with ipconfig /all

I am not using ICS, I am using NAT on a firewall/router, but the DNS server
is out in front of it (with a software firewall on it)

Well, one huge error I see is that this machine has two gateways. So
apparently what's going on is a routing issue. On any given machine, you
need to only use one gateway. It's kind of like saying the gateway is "the
way out of the building". If more than one is listed, then confusion can set
in. Apparently this machine (which is not running NAT, since you said your
router is doing that) is sitting on your two subnets. My suggestion is to
use the internal gateway, 192.168.0.1 so your control is from the internal
network. If you want to use the external gateway, 209.161.4.73, then you
have to create a static route so the external system knows how to get to the
private network, but since it's being NAT'd, I would just suggest to use the
internal gateway and remove the 209.161.4.73 address.

I don't think I can get rid of the 209.161.4.73 gateway, as its the IP of my
DSL modem. If I were to get rid of it, then the clients would have no way
to get out of the internal network, correct?

You have to remember, as a hosts sitting on the internal network (since it
has an IP on the external network) will be able to get out of the network
with the gateway on that intenral network as the other clients on the
internal network are getting out.

You just cannot have two gateways on any one machine or you lose outside
connectivity. It's just a rule. Choose one or the other. My money is on that
you need to use the internal one.
