Hello,
I have a problem with one domain.
I cannot send emails to *@pdvsa.com
I have 2 DNS server, but this zone is just installed on the second DNS server as primary zone.

Do you know why ?

if you hold the zone in your dns.. and you mail server queries your dns servers , then it's obvious to create a correct MX record in that zone..

hope this helps

The mx record is in that zone.
mail.pdvsa.com
Prio 10

But why I cannot ping or resolve this ip ?

if you query your second dns server , the one with the pdvsa.com zone in it , you fail to receive an answer ?

nslookup mail.pdvsa.com 2ndserver.com
nslookup -q=mx pdvsa.com. 2ndserver.com

these doesnt respond with an answer ?
you should verify that the correct dns server is first in priority & that you ipconfig /flushdns first .

Both,

nslookup mail.pdvsa.com 2ndserver.com
nslookup -q=mx pdvsa.com. 2ndserver.com

is working.
But when I put nslookup mail.pdvsa.com 1stserver.com then I get an error.

What is the problem ?

you should either configure 1stserver.com to host the zone also , or configure Contitional Forwarding for the pdvsa.com domain on 1stserver.com. that is forward request for this domain to a specific server.. 2ndserver.com :)

here's a nice how-to conditional forwarding

let me know this works..

ok or is it better to delete the zone on dns2?
And create a new activedirectoryintegrated primary and secondary zone for pdvsa.com?

well, yea that would of course work.
i didn't want to force you to change anything :)

but if you do want that zone to be replicated and as secure as it gets - AD integrated is the way to go.
as long as you solve your issue.

ok, about your solution.
I have configured the forwarders.
But this will not work here.

I have entered the doamin : pdvsa.com and the IP of it.
But I cannot resolve it.

Can this happen, because this zone is just installed on DNS2 and is not replicating to DNS1 ??

the ip in the conditional forwarding should be the ip of 2ndserver.com.
and you configure conditional forwarding on 1stserver.com.

that is the purpose of DNS forwarding. a dns server forwards requests for zones it is not authoritative for.
conditional forwarding allows you to forward requests for specific domains (zones).
