Re: DNS Across subnets

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Did you get this fixed? Just to elaborate: from a simple networking point of
view your http://copier is having the domain name appended and being
resolved correctly by DNS. If you were just routing to the copier VLAN the
request would be answered. But you are going through a web proxy, Squid.
Squid is looking at the header of the http request and instead of saying
"that must be local" it is saying "never heard of that domain". It is a
misconfiguration in Squid that is causing your request to fail. That's my
guess as to what is wrong,

If you get those results to the ping and http consistently from any
machine in VLAN2, then:
- DNS is set up correctly
- the domain suffix is set up correctly in the client tcp/ip properties
It looks to me as though your Squid web proxy is not handling local
requests correctly.

IE does not use a proxy server. Here's the error message: (By the way,
I
don't use caching on the firewall)

The requested URL could not be retrieved

----------------------------------------------------------------------------
----

While trying to retrieve the URL: http://phones/

The following error was encountered:

Unable to determine IP address from host name for phones
The dnsserver returned:

Name Error: The domain name does not exist.
This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
Your cache administrator is webmaster.

Can you post the whole error message?
Can you set your IE browser to not use the proxy server (if it does)?

When I ping it from vlan2 it does resolve and the domain suffix is
appended.
http://copier.mydomain.com does in deed work. It's just the
http://copier
that doesn't work. I do have a firewall on my network, and actually
the
error page that comes up appears to be generated by the firewall.
However,
i believe the firewall is setup to allow all internal traffic.

What you have described should work.
1) When you ping "copier" from VLAN2, is the domain suffix appended?
If
yes,
is it resolved. If it is resolved, is there a reply? Does
http://copier.mydomain.com also not work, or just http://copier?
2) Are you using a proxy server? Is there a firewall or access list
between
the subnets?

Background: I have four VLANS. Each VLAN has it's own Windows
2003
Server
that functions as a DHCP server along with WINS and DNS. They are
all
part
of the same domain, and each a GC.

VLAN1 gives out ips of 10.0.x.x
VLAN2 gives out ips of 10.1.x.x
VLAN3 gives out ips of 10.2.x.x
VLAN3 gives out ips of 10.3.x.x

On VLAN3, I have a copier/printer that has a built in web
interface.
I've
assigned it a static IP of 10.2.0.5. In the DNS server on VLAN3, I
made
an
entry for that machine. So now, if someone goes into Internet
Explorer
and
types "COPIER", it resolves to 10.2.0.5 and displays the Web
Interface.
However, that only works for the computers that are physically
connected
to
VLAN3 (as untagged). If I go to a computer on any of the other
VLANS,
I
get
a page that says "The requested URL could not be retrieved".

When I look at the DNS running on the other servers, everything is
replicated.

What am I not doing that is preventing this from working on all
VLANS?
