Re: sys vol check

I modified the forwarders tab on the DNS AD list like the intructions listed,
and then I changed the DNS servers list on all three DNS server to point to
each other rather then the ISP DNS servers.

When I got in this morning, no one was able to log on and see the network. I
had to undo everything I did yesterday afternoon and it seems to be working
fine now.

I am not sure what I did wrong. I followed the instructions listed in the
microsoft link you sent me earlier.

how?

The DNS server should point to itself in NIC Preferred DNSserver.
The clients should use only their local DNSserver in ther NIC Preferred
DNSserver.

How clients and servers are configured now?

I have done as you instructed and it crashed our network. No one is able to
log on this morning and see any local resources.

- Remove what?
- If you're referring to network clients, make sure that each client only
uses their local DNS server, DON'T Place ISP DNS server on clients NIC
Preferred DNS or secondary.

2. Why don't I want the ISP DNS servers listed? We have a hard time
accessing the internet without them there.
Only local DNS servers should handle Internet name resolution, trust me,
you
don't want your clients and member servers trying to register on external
DNS servers, or trying to resolve public address in public domain,
remember,
the AD is DNS dependent and all clients need DNS resolution to reach AD
Servers,etc... That's why they must use only internal DNS servers, and,
if
the clients need Public resolution then internal DNS servers should
handle
that. You may think of internal DNS like something of this way...
Internal
DNS servers are maestros of Internal and External resolution... If the
clients need to access AD servers the Internal DNS provide the correct
address, if the clients need to access to public domain, the internal DNS
should also provide them the correct address. What would happen if you
configured ISP DNS servers on clients??? Well, First the ISP DNS Servers
don't allow your clients to register on their DNS servers, Second, the
ISP
DNS Servers don't know where your internal DCs are, Third, if your
clients
go outside trying to resolve DNS queries they're exposing to public
network
which represents security issues.


3. All three offices are serviced by COX, but each office has their own
ISP
DNS server addresses because of their geographic location. Will doing
this
step ruin the connection to the internet?
Why? If you have Internal DNS in each location (site), configure
Forwarding
in each DNS server to point to the correct ISP/DNS Server, you can even
increase security by point the Forwarding to router IPAddress.

We have three different DNS servers, 1 in each office. I have modified
the
DNS FORWARDERS per your suggestion. I have several questions about
that.
1. How do I know when it will be safe to remove them from the DHCP
device
that is handing out licenses?

2. Why don't I want the ISP DNS servers listed? We have a hard time
accessing the internet without them there.

Hi

First remove the ISP DNS servers from your NIC configuration.

To resolve internet names configure Forwarding

Second sounds like your server isn't resolving the parent domain, to
solve
that make sure that your server can resolve the FQDN of the DCs at
Root
domain. You can configure Conditional forwarding, Secondary zones or
you
can
replicate the root DNS Zone at forest level. Attention the
_msdcs.domain.tld
contain information about Global catalog and other domain/forest
important
records and they only exist in parent (root) DNS server (this zone
contains
information that IS ONLY AVAILABLE IN THE ROOT), so is always a good
practice to replicate the root _msdcs.domain.tld across the forest.
