DNS problem in SBS Network
Posted on 2007-09-28
For the last month we have been getting internet drop outs and I think it may relate to a DNS problem on our server/network. I have called up our ISP and they have already checked the ADSL line that we use and given it the all clear fault wise. Our SBS server has two DNS forwarders configured and each client pc has static IPs and the server as the prefered DNS server.
The reason why I think this may be a DNS problem, is that I have tried to ping IPs and they all return successfully while using http://www.domain.com fails. The problem seems to be intermitent and will last for 5-10 mins then IE7 will accept domain or IP. Does anyone have any ideas as to what may be happening?
