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 .co.uk 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?
