Does DNS Replication issues cause user issues?

Recently our corporate office created a VPN tunnel between our PDC and one of
their servers. Our server is running Server 2003, DHCP and DNS. Everything
was working fine (user permissions, users seeing printers etc..) until
corporate made this change. I ran netdiag and while I don’t have the exact
error message, my DNS server 192.168.7.2 reports back fine, but then it says
there is a fatal error connecting to corporate’s server, 192.168.1.7.

Would having this DNS error cause user problems inside my network? I did add
a new user a couple of days after this change and while his permissions are
set correctly, he is unable to access any of the share drives or browse my
server through My Network Places.

If this is causing my problems, I will have corporate resolve this.

Thanks,
 
Re: Does DNS Replication issues cause user issues?

Brad,
You will need to be more specific and what you have set up and what errors
are occuring to get anything useful,
What do you mean by a VPN between a DC and a remote server? How is the VPN
created?
What is the connection to the remote server for? What has that to do with
DNS replication? What errors are your users experiencing, or is it just one
user? etc

Re: Does DNS Replication issues cause user issues?

Hi Anthony, I'm not really looking for resolution to the problem, but just in
general will DNS problems cause users to experience problems?

Here is the situation:

Our office is located in Cincinnati, OH and the corporate office is located
in Kansas City.

Prior to Sept 4th, our network was completely isolated from corporate (this
is a franchise business) and we operated as our own entity (network wise).

Then Sept 4th, we became the "Beta" site for a Microsoft CRM Package that is
being hosted by our corporate office. So, they sent us a Watchguard VPN
Router that created a VPN tunnel between our network and their network.

Corporate then created a domain trust between our only Server and one of
their servers.

My server's IP address is 192.168.7.2 and points to itself for DNS, but
Corporate added their server, 192.168.1.7 as the secondary DNS entry onto my
server.

Nothing in the Event Logs show their is problems with the DNS, however when
I run: netdiag it comes up with an error that my DNS could not communicate
with their DNS server and came back with a [Fatal Error].

I also ran: dnslint /ad 192.168.7.2 /s 192.168.1.7 and it would come back
with an error of something like "no authorative domain" or something like
that. I'm not at the office right now and I don't have the exact messages.

My new user is a sales rep and he's been added to the sales group. I have a
script that automatically maps both a Sales Drive and Office Drive. When
these 2 drives are mapped, he can access them just fine.

He can see the share drives by going to Windows Explorer and going to
\\Cinci\. However when he clicks on the Sales Drive or Office Drive (from the
share) he is not able to access them. It comes up with an error of "doesn't
have permission or cannot communicate with server" or something like that.

So I'm just wondering in general if there are DNS problems, will this cause
problems for users. Thanks.

Re: Does DNS Replication issues cause user issues?

Yes, that's the information I was referring to.
Watchguard VPN: no reason for this to cause a problem. Your original post
may have been referring to a dual NIC on the DC, which is why I asked.
For the trust to work, you need to be able to "find" their DC's, which means
resolving their DNS zone. Putting their DNS server as an alternate DNS
server (I assume that's what you meant) in your DC network properties is not
the way to do this, and will cause problems on your DC. The right way to do
this is to create a secondary zone in your DNS server of their DNS zone.
This won't affect your clients' resolution, as they are using the DNS
server, not the networking properties of the DC. However it will affect the
DC.
What I would do:
- make screenshots of how it is
- make a note of the errors
- take the alternate DNS server off your DC
- ask them to come back and set up the trust properly.
Just an additional point: who is trusting whom?

Re: Does DNS Replication issues cause user issues?

I will do as you suggest. My corporate IT is looking into it now.

They setup the trusts, so I'm not sure who is trusting whom.

Thanks for your help Anthony, it is greatly appreciated!

Re: Does DNS Replication issues cause user issues?

Hi Anthony,

One more question, could licensing be an issue? We have the standard 5 CALs
that came with the server and this new user would be our 6th user. If all 6
of us are logged in, could this be causing problems? If it is, we will buy
the licenses, but we are using these licenses as Per user or Per Device Mode.

The corporate IT guy is thinking that the DNS issue that I explained below
isn't causing the issue. Thanks.

Re: Does DNS Replication issues cause user issues?

Hi Brad,
Glad to help. The reason I ask about the trust is:
- if they are trusting you, then fine, but who else are they trusting and
could those other people potentially end up connected to you?
- if you are trusting them, what protection do you have if something bad
happens?

Also, the Watchguard VPN is a nice easy way to make the connection, but if
they do the same for everyone, how do you know who has access to your
network? I would be inclined to put the Watchguard box on a separate DMZ of
your network, with no access except through your firewall. That way, for
example, you remain in control of who has access to your network.
Anthony,

Re: Does DNS Replication issues cause user issues?

Hi Brad,
If we are talking about Windows CALs and not TS CALs then no.
We didn't discuss in detail what actual errors you were getting. But having
an alternate DNS server that does not contain the AD zone is a bad idea.
