Hi,

Thanks in advance for any . Here is my issue. I have a
registered domain name let's call it services.com. Verizon hosts DNS
for this domain and basically holds MX records and A records for mail
in which they host as well.

I have created an internal Windows domain called the same,
services.com. All of the email clients use pop3 for email and use the
DC/DNS server for DNS. I added A records that point to the correct
addresses for pop.services.com and smtp. services.com. It seems to
work correctly when pushing a pop client to check for mail most of the
time. Every once in a while though the client will time out and say
that it cannot find the server or there is a Socket Error. Is this a
DNS issue?

If so, is there a way for me to configure DNS to forward requests for
services.com that are not able to be resolved locally out to the
Verizon server for resolution? Or am I off base with my issue? Or
should I not have named the internal domain the same as the public
domain?

Thanks again!

Mike

This is called a split zone, split horizon or split brain. Choose your
favorite. Same internal/external name.

You can simple create the www or whatever records you like internall and
provide the actual external IP addresses. To find them, use nslookup but you
need to change focus on which DNS server it is using to resolve. You can do
it this way:

nslookup
server 4.2.2.2
www.domain.com
It will show you the IP(s)

What is easier is to delegate www by right clicking domain.com, new
delegation, type in www, then provide the name servers. They can be found
by:

nslookup
server 4.2.2.2
set ns
domain.com
It will show you the nameservers

I like this better in case the ISP changes their webserver IP address and
some are known to do that often.
