I'm baffled over this issue. We just had our Verizon DSL line be switched over to Frontier, as that's happening a lot from what I hear. Since we have a static ip, we were given a new one. Since that change to the new IP, we are having problems browsing the internet. Pages would be slow to come up or not come up at all. We figured it was something to do with Frontier's DNS servers as our VoIP system was working fine as well as FTP and things like that. We could also get to websites just fine using the IP, so DNS is a good bet. We then switched to Comcast (which got us 7 times more speed for only $40 more a month) so we are sitting at about 20 Mbps up and 8 Mbps down per speedtest.net. Got a new IP from Comcast. Upon setting all that up, the same thing is still happening, pages are slow to come up or not at all.
We are on a Windows network here with a domain controller running Windows Server 2008 Standard. Could it be DNS issues on the domain controller? Since that's what our local machines are going through? If it is that machine, what can I do to fix this problem? It's irritating to have fast internet and not be able to use it.
