http://www.dt2009.gov/ can not be found from my DNS Server. Is this an internal URL ? Did you already tried the Firefox safemode ? http://support.mozilla.com/en-US/kb/Safe+Mode
do you have Proxy Auto Config configured? (or a proxy, however that's less interesting)
Probably meant https://www.dtv2009.gov/ (US government DTV transition website) dt2009.gov says "Registered And No Website" in Whois. dtv2009.gov loads fine for me.
As per comment 3, dtv2009.gov loads fine and dt2009.gov domain does not exists. Marked as INVALID.
