There is probably a really simple solution to this that I am just completely missing the solution too... hoping someone can help.  I work for a law firm, and for some strange reason nobody in my office can access http://www.uscourts.gov.  We need that site to work for court filings etc.  I can bring it up when I remote into my home computer, I can even bring it up on my Servers (Windows 2003).  However, no "client" on the network can access the site.  All other websites work just fine (well at least no one else has mentioned any other sites that don't work).  I've tried to access it on Windows XP Sp1, Sp2 Desktops, a Vista Ultimate Laptop, and a cleanly installed XP Laptop.  DNS problem maybe?  I really don't know.  Any help would be appreciated.

Sounds like a dns issue to me.
to verify:
at command prompt type "nslookup," then "server"
this will echo the DNS server you normally use (may be an internal DNS server).  Try to enter the dns name,"/www.uscourts.gov" if you don't get a response, remote to you home computer and find out what dns server IP address it is using.  Back at the office type "server <IP address of home DNS server>" to connect to that DNS server and again enter the dns name,"/www.uscourts.gov"  if you get a response then it is an issue with your dns.

if this is the issue you can then find out what you internal dns forwarders IP addresses are, and repeat the process.

If you have internal DNS servers you can work arround this issue by creating a dummy zone for www.uscourts.gov pointing the the IP address of the site.

ah, another issue.  I added a A record for www.uscourts.gov with an IP address of 207.41.14.192... and am able to open www.uscourts.gov on my computer now.  But, there are a lot of 'sub' websites within www.uscourts.gov that I still cannot access.... like www.cand.uscourts.gov, and ecf.cand.uscourts.gov.  Is there a way to make sort of a wild card entry for all *.uscourts.gov websites?  Or do I have to put in each one manually?  Thanks.

just a quick update since i'm under the gun on this... i added another A record for ecf.cand.uscourts.gov with it's IP address and am able to get on that... but when i tried to add one for www.cand.uscourts.gov with it's IP address it still goes to www.uscourts.gov.  I tried creating an entirely seperate zone for cand.uscourts.gov but it is still going to www.uscourts.gov.
