We have a small network with some clients of different OS and a Win 2003 SBS Server.
The installation is quite normal and the server has Active directory and dns server enabled.

The problem is that the client (and also the server itself) quite often are unable to browse webpages. After a while or next day it can work.
I have narrowed the problem down to dns resolution. Client use server IP as only dns server. Changing this (not allowed for active directory connected clients, I know) to an external DNS server solves the problem. Ping an external IP directly is always possible so network connectivity is also good.

I'm thinking of just clear the dns cache of the server, but I'm note sure this is the final solution.

What is your idéas?

I forgot. Adding a forwarder in the dns-config at the server fix our problem too. So there are some problem with the dns resolving of external addresses.

Some clients have static IP and some of them using the dhcp server to get their IP-addresses.

Sounds more like a resolver issue.

Have you run the Connect to the Internet Wizard?

Can you also check in the DNS management console, right click the server name select properties then click the forwarders tab.

Do you have your ISP DNS servers listed?

If not put them in.

The gateway address should be the router unless you are using the SBS server as a router which from the question it doesnt seem like it is.

It is a resolver issue for sure.

Some people recommend to use forwarder and some do not. I think a 2003 server should be able to resolve by itself without using a forward dns s erver.

But the resolving gets better if I add a forwarder (I have tested that).

Gateway is the router, the SBS is just acting as dns server

I ALLWAYS use forwarders because i find root hints unreliable.


Mainly because of performance why would you ask your server to do something that can be forwarded on to someone else to do?

"Mainly because of performance why would you ask your server to do something that can be forwarded on to someone else to do?"

One reason would be that my local server would be faster to answer than an external dns server at my isp. But in reality it might be impossible to see the difference???

Only if your local server already has tge answer, if it doesnt your asking IT to find it instead of your ISP's DNS server.

I was involved in a question a month or so ago with a couple of the top Active Directory experts and all 3 of us agreed that we ALLWAYS setup forwardersbecause they are more reliable.

And you yourself are witnessing this!

You are probably right. I will add my ISP dns server and see if thing gets better over time. Thank you for quick and helpful answers.

I always try to give answers where possible based on my own experience.

I have several customers setup this way and we never experience problems with DNS lookups.

When i get called in to look at a potential connectivity issue its one of tge very first things i check.
