SBS 2008 / Exchange Server Problems

Posted on 2010-11-23

  It has been running fine for two years. Two days ago messages started getting stuck in the queue, I am on FIOS so I am using smtp.frontier.com as a smarthost. I look at the queues and the messages are stuck in the smtp.frontier.com queue with the last error on the queue being "451 4.4.0 DNS Querey Failed".

   I am going to say nothing has changed on the server but obviously something has. I have no idea where to start on this. I found an article that said to download and install Rolluo 3 for ES 2007 to correct the problem but that patch won't even install.

Help!!!!!!

The usual issue with DNS on SBS 2008 is either a lack of DNS forwarders on the Forwarders Tab of DNS Server Properties or that the DNS servers have changed.

Please check yours - check with your ISP for their current DNS server IP Addresses and make sure your forwarders are either correct or if none, add the current ISP's forwarders.

That should hopefully sort you out.

  Thanks Alan. I came across that too. The forwarders were not changed. Thinking Frontier might have their DNS servers messed up (they have been on a path of death and destruction lately) I added a couple more Verizon DNSs (4.2.2.1 and 4.2.2.2), moved them to the top of the list and the problem persists.

Okay - what are the DNS settings on the SBS server?

It should be set to look to itself to resolve DNS (i.e., the Server IP Address as the Primary DNS server).

Can you resolve smtp.frontier.com in DNS from your server in a command prompt?

Alternatively - if DNS is not working - for now change the FQDN for the SmartHost from smtp.frontier.com to the IP Address of 66.133.129.50 and then you don't have to resolve the name!

The NIC DNS is pointing at itself. I can resolve smtp.frontier.com from the server. Very funny. I changed the smarthost to 66.133.129.50 and that seemed to do the trick. I am going to run with it and see what happens. Thanks!

No problems - at least it gets you out of hot water for now.

Thanks for the points.
