I set up a simple Bind server on my VPS and it is working properly.

The problem occurs with my local windows machines, which are connected to internet through the home router.

I created an A-record named 'dev' and it is invisible from my local network for some reason, though people from other locations can resolve dev.mydomain.com. Ironically, dev.mydomain.com cannot be resolved for myself only.

If I add another A-record, say, 'gamma' then it becomes visible from my local windows machines instantly. So this is just for that particular 'dev' name.

The only difference is that I had dev.mydomain.com server on another IP but that was a month ago; all nameservers have been changed since then. I tried to reboot my router and flushed dns cache on windows machines: no result.

Thank you in advance.

Perhaps a cached negative hit? Try ipconfig /flushdns to clear the client cache.

Edit: Summing up the findings so far.

  • You flushed the local DNS cache, so there weren't any cached negative responses. This means that the problem is not with your client.
  • You queried the nameserver directly from the client and received a correct response. This means that the problem is also not with your nameserver.

The logical consequence is that the cause of the problem lies somewhere en route between your client and your nameserver.

Which DNS server(s) does your client use? (ipconfig /all) Is it your router? What happens when you configure a different nameserver on your client? (e.g. 8.8.8.8, one of Google's public nameservers)
