Internet is very slow; we have a static IP
Posted on 2011-10-14
The internet is very slow. It started about 24 hours ago. We run Windows SBS 2003 on our server. We have about 20 work stations running XP Pro. The DSL line is a telephone line. It comes in to the modem. The modem is in bridge mode. It connects to the Belkin router which also a wireless access point. The router connects to the switch. All the other computers connect to the switch. We have a static IP address with our ISP. I contacted our ISP and I don't think it's their problem. It seems as though it might be a DNS problem. The work stations point to the server for DNS. The server's DNS is itself. The default gateway is the router. In the router configuration the DNS address is for a reputable DNS server, though I tried several others with no improvement. If at a work station I bypass the server by pointing it directly to an outside DNS server, then the internet snaps to attention and works great. (Of course we cannot do this in practice because the physical server is the email exchange server, it's the file server, it manages antivirus, etc.) But this tells me that the problem is not with the ISP. It seems to me like a DNS issue. Could the router be faulty? I rebooted the router and the server.
