Windows 2003 DNS server is not 100 %
Posted on 2010-01-10
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?
