I have a Mac OS X Lion laptop and a Windows 7 machine on my network. I can access a website from one, but not the other. When I try and access this website from my Mac Safari says it cannot find the server. I have Chrome installed on the same machine and it cannot find it either.
I checked the DNS settings, adding a couple more servers to the list but this didn't help (I reordered them so I knew it was using a new DNS server).
I also flushed the DNS cache using the following command in terminal:
That did nothing. Finally I cleared the cache in Safari, that did nothing.
Any ideas? I had a problem with this host before putting my IP on a backlist, which I was able to confirm by going through a proxy - but this time the Windows PC is okay, and they are both behind the same router and same IP.
