It would appear that your DNS server is having issues. Using the plain language "www.forces.gc.ca", you're not having any luck because you have to use DNS to resolve that to an IP address. If you use a direct link (
131.137.250.121) to the IP address like I gave you (removing the need for the DNS service), you're successful. You're able to get to the Forces' main page, because it is on the same network as the IP address I gave you. The Recruiting website is on a different network (
208.85.114.196), so your computer has to consult DNS to find it - and it's not being successful.
Just out of curiosity, what DNS addresses are you using? (follow the instructions
here if you don't know how to find out using XP/Vista/Win 7).
Don't list any of the other information, such as your IP address.
Bear in mind that if the IP address listed points to your home router, then your router is probably configured with your DNS settings and you'd have to log into that to find out its DNS settings. Also, what ISP are you using?
My ISP doesn't have very reliable DNS services, so I use
OpenDNS. There is a free service that you can register for, but truth be told you don't even need to register and can just use the DNS server addresses at the bottom right corner of the main page for OpenDNS, replacing the DNS addresses you're currently using. I have those settings in my router, and I have all of my home network PCs pointing towards the router for DNS server information.
