Sounds like your DNS server cannot resolve the name www.komando.com

Does the ping bring up an IP when you attempt the ping?

See if you can ping other servers by name.  Try nslookup www.komando.com and see what comes up.

www.komando.com  resolves (right now) to 66.210.246.140  

I can't ping that though - not a big surprise.
