Exchange and DNS problem, email is not working.
Posted on 2007-10-01
Let me take a minute to describe my network. I have two Windows 2003 servers, one is an Exchange 2003 server and the other is a Domain Controller. All computers on the network are running behind my router/firewall in a private ip address range. I only have one public ip address which is configured on my router along with my ISPs DNS servers.
We have a public website that we pay someone else to host for us. Thursday morning last week we changed web host providers. I asked our new provider to create the following records:
Record FQDN Record Type Record Value MX Pref
mail.domain.com A 199.x.x.x
domain.com MX mail.domain.com 10
These are the same records that our former web host provider hosted when the email worked. Our web site is back up but our email is still not working. From my home, if I open a web browser and type the ip address\exchange I am able to reach our email server through OWA.
I know this is a DNS problem but how do I fix it? If I do a nslookup for my mail server, mail.domain.com I get back:
But if I do the same for the ip address the following is returned:
How do I fix this?
