I use Gradwell.com to provide secondary DNS but I keep getting e-mails along the lines of the following saying that it's not working:
You have asked us to provide a secondary DNS service for the following domain(s) Unfortunately, the primary DNS server(s) you specified are not permitting the necessary zone transfers from our servers, or they are not answering "SOA" queries for your domain correctly.
I have gone through the support procedure and they weren't that helpful. They have suggested the following:
Our secondline team have suggested setting the AXFR to use anouther machine. This will ensure that the transfer is not locked down to one machine and should allow any machine to make the request
I don't really know what AFXR is and I only have 1 production machine so I can't set the AFXR to use another one!
In previous support correspondence we confirmed that I am allowing transfers to the correct IP and that I have the correct ports open on the firewall.
I am running Windows Server 2003.
What can I do to try and get these zone transfers working?
