Same ISP New IP addresses and DNS, now workstations have DNS issues.
Posted on 2011-03-22
I recently added a block of IP's from the same ISP (Comcast). We had a single IP before through them, when we added they gave me new DNS addresses which I am using at another location without issue. The problem that I have is that within the network, users that are hardcoded, using the firewall which works as a DNS proxy and the server running DNS cannot get to websites, ping IP's all day and can get to one or two sites. If I change them over to DHCP, let them auto obtain, it works fine and then I can hardcode right back to the original settings and they can get on fine after that. I've tried ipconfig /flushdns and repair the connections with no luck. Any ideas??
