Internet problems on a SBS 2008 server network

Posted on 2009-05-01
Last Modified: 2012-05-06
I have over the past few months installed 4 new SBS 2008 servers. But all 4 servers have the same problem. For a few days everything works fine, then out of the blue some websites cant be viewed. During this time it seems that .com sites work fine but do not!! To fix the issue I run the ICW, its then fine for a few days. Then it all happens again.
I can only think its something to do with the DNS, but I cant work out what.
Has anyone come across this before?
Many thanks

    Root Hints.

    Setup a Forwarder to your ISP's DNS server rather than relying on Root Hints.

    If you have a root zone in DNS (".") then delete it to activate the Forwarder tab.

    Forget the ISP's DNS (good idea, but depending on the ISP... can be frustrating)
    Forward to (no affiliation other than a satisfied user). It's free and extremely robust.

    Expand down to the servername - including that.
    Right click the servername and select Properties.
    Forwarders is a tab.

    If it's greyed out then you likely have a root zone in DNS ( the Forward Zone is a period "."), delete this zone to activate the Forwarder tab.
