I've run into this issue repeatedly in the past week. The problem (in my cases at least) appear to be Shaw's DNS servers. For whatever reason, they are not responding for some names, and not forwarding requests to other servers.
For me the solution has be change the DNS servers in use. For my internal network, I've switched to point to my private instance of BIND (used solely to resolve internal names), and things work well enough. For boxes outside my network, I've switched them to use the OpenDNS servers (www.opendns.com). In both cases, everything went back to normal. In ALL cases, it has been a Shaw DNS server. I discovered this while trying to fix the issue for some friends of mine. They were behind a DLink box, and using DHCP from that box. I determined what DNS servers the DLink was using, and tried to access them directly from the workstation. I could ping them, but when using them as the workstations DNS servers they failed as well. I next ran nslookup and tried to resolve the host in question. The response - from Shaw's server (identified by name) was that the name could not be resolved. Ergo, trying a different server fixed the problem. I knew it was not due to a change in the domain name, as we control that and hadn't done any changes in more than a year. A little wordy for a response I know, but hopefully this helps out....
