Re: Yet another multisite VPN DNS question!

You can still use it. You just need to set an ip helper address in the
router to tell it where to forward DHCP requests to.
Reverse lookups are used mainly by management software to make log files
easier to read. They are easy to set up and you may as well do so, but they
are not required.

What if I'm unable to use Windows DHCP service, due to some locations not
having a local server onsite?

And this may be unrelated to my problems, I'm not really sure.. What if I
have no reverse DNS entries on my 172.20.x networks? I have entries in the
reverse lookup zones for the nameservers and SOA, but that's normal. I
have
no reverse entries for workstations. Should they be there?

Thanks!

Jason,
It looks as though you just had some obsolete registrations in your DNS
zones. If you delete them manually from forward and reverse zones it
should
be OK. This just happens if a machine does not remove its auto
registration
and another machine takes the same IP address. You can set scavenging to
remove old registrations. If this is still a problem you can use the
Windows
DHCP to do the registration for you, as it will have the rights to delete
the old computer registrations.
I think the 172.1 address is just a wild and futile attempt by the client
to
find an authoritative name server,
Hope that helps,

This is starting to really confuse me.....
This morning when I wrote my last reply, I had deleted the entry for
Station04 in DNS and then from the workstation ran ipconfig
/registerdns.
That's when I got the EventID and error I pasted.
Now when I do it, it works. Also, I compared DNS entries with an ipscan
of
my network, everything is matching up.

But I haven't changed anything since yesterday!! hehe.. go figure

Well, in response to the ipconfig /all, it basically looks like this:

Dhcp Enabled - Yes
Autoconfiguration Enabled - Yes
IP Address - whatever is currently assigned via the Cisco DHCP server
Subnet Mask - 255.255.255.0
Default Gateway - IP address of my Cisco router
DHCP Server - IP address of my Cisco router
DNS Servers - IP address of DC/Exchange Server as Primary; IP address
of
PDC
as Secondary

Really nothing out of the ordinary there. 172.1.1.1 exists absolutely
nowhere on my network. There is only the Cisco router and the Win2k3
Server
that have DHCP capabilities on this subnet, and the Win2k3 service is
disabled. Everything else here is WinXP Pro SP2 and my Vista Laptop.

What I noticed about that 172.1.1.1 deal when I Googled for some info,
is
that just about everyone else who gets EventID 11163 has the same
number
appear. It takes the first section of their subnet (be it 192, 10, or
in
my
case 172), then follows with 1.1.1. Very odd, in my opinion.

So basically, I'm not sure if my DNS registration issues are resolved,
or
if
they're going to reoccur as of yet. I guess I'll keep tabs on it and
see
if
everything is staying in line or not.

Thanks for your help with everything so far, I really appreciate you
taking
your time to look at this with me!

Jason,
Can you find out what 172.1.1.1 is? It looks like a gateway device.
Maybe
you have another DHCP server operating on the network. Can you do an
ipconfig /all on a workstation that is getting an error?
