I have a Server 2008 domain controller with Virgin fibre as the internet provider. Lately they have been losing webpage access from time to time (RDP, Office 365 still connect so it is just the abilty to browse webpages).
The Virgin hub is set to modem mode and is connected to a Draytek 2820 which has the latest firmware. As a test last time they lost webpage access I remoted in and restarted the DNS server on the Server 2008 box and that fixed the problem (for now).
I cant see anything in the event viewer that points to a DNS issue - does anyone have any advise on this problem so that a permantent fix can be made?
