Setup Exchange 2010 cannot verify Host (A) record warning
- by Joost Verdaasdonk
When I try to install Exchange 2010 on my server 2008 R2 server I get a warning during the prerequisites check:
Warning: setup cannot verify that the 'Host' (A) record for this computer exists within the DNS database on server: 90.195.200.12.
The goal of this Exchange setup is that I'm able to sent email in my local domain as well receive/sent email through the public domain name.
Some information about my setup
This Server is going to be a dedicated exchange host and has the following IP setup: (IP's are examples and not the real IP's ofc)
Local VLAN NIC:
IP: 10.10.50.22
Subnet: 255.255.255.0
No gateway
DNS: 10.10.50.1 (is domain controler with authoritive DNS)
public WAN NIC:
IP: 90.195.200.148
Subnet: 255.255.255.235
Gateway: 90.195.200.145
DNS: 90.195.200.12 | 190.160.230.14
My public domain - exampledomain.com
A record: mail - IP: 90.195.200.148
MX record IP: 90.195.200.148
As I'm seeing now the exchange setup is looking for the A record in one of the DNS servers in my Public WAN NIC.
And ofc this is not where my A records are defined. I have those A records in 2 places:
1. In the domain controler DNS (the private nic)
2. In the online dns registration of my public domain (exampledomain.com)
My question is... is this warning going to be a problem? Can I do something better in my setup so that this warning will go away?
Please advice?
