We are running a new Lenovo ThinkServer with SBS 2011 Essentials for server software.
We just installed this a few days, and since then, we have been having internet problems. The router/modem shows that we are still connected to the internet, and we are able to access the internet, but each web page either loads very slowly, or fails to load the first time. Google Chrome gives us this message:
This webpage is not available
The server at www.paypal.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
After a refresh, it usually works. Any thoughts? We were not having this problem a few days ago with our older server.
