DNS problems

Hey, a bit of advice if you can, I am a newbee at dns.

I have set my router up with a dynamic dns setting and registered offsite, but I have a dns server of my own on my enternal network for whiich I run my own domain. when I do a lookup for my internal dns, it works fine. but my external dns doeent resolve. I am really stumped on this.................

Welcome to Dev Shed.

The more info you provide, the better... I'm not entirely sure on what the problem is, but let's see what we can find out:
1) What OS are you running?
2) What DNS server are you running?
3) When you say you're external DNS doesn't resolve, what do you mean? I'm assuming that external to your network, the DNS isn't resolving properly...
4) Have you forwarded port 53 in your router?

1 running xp on my lan clients, and 2003 server as my primary domain controller with dns. If I cmd nslookup google.com, I get a reply and resolved no problem, but as soon as I try and nslookup traton.dyndns.org whjich is my dns, it dosent understand it. I have not set up any forwardsto the router, sorry to be vague, but am quite new to dns.

In your router, have you set it up for dyndns? A lot of routers offer the option to sync up with a dynamic dns provider.

Also, log in to your dyndns account via dyndns.com and make sure it's displaying your IP correctly. You may need to update the IP from within the account.

thanks, I will try that now, I have setup my router to to to dyndns, but I'll check my account settings as well.

No problem... Let us know if that works. If not, we'll see what else we can do to get it working for you.
