I would like to know the answer too. Anyone here know what is the right answer to your question. I'll do some investigation and get back to you if I find an good answer. You should email the people at 123 reg as they probably can help you..
Hi I have tried to delete and recreate the name servers using the manage child name servers but I have had no luck, I also asked my server provider to login in and have look and they couldn’t see any problems. That’s when I contacted WHMCS there response time for domain name is not great. So you agree with my server provider that it is registrar end may be they aren’t just trying to end the instant chat. Lol.
Thanks for your help.
I think you need to do a couple of things..
First, do a 'whois ns1.yourdomain.com' on the shell, paste us the output..
If it does not exist, you may not have registered the dns servers at your registrar..
Second, do a 'dig A ns1.yourdomain.com', to see if the a-record resolves..
And finally, it would really help to know the domain, if you feel like it you can message me it and I can do a little rundown of the DNS...
