If it's just one system,create a shortcut to the page on the desktop with the right information.
That'll take care of it nicely, and the Air Force won't get upset.
HTH!

Toolmaster...
I'm impressed...congrats. You have many Certs! I'm working on my CCNA cert currently. Did you find this one to be the most dificult? I am finding it to be the worst so far!

Thanks... <Blush>
CCNA is big on networking, which I used to do quite a bit.. Wasn't that bad for me.
I'm one of those professional geeks. LOL.

ECPunk,
Actually port number is an unsigned short variable that ranges from 0-65535.(0x0-0xFFFF). Which is the total of 65536. And no, it is not doubled, if you have a udp server (also referred as "connectionless") running on echo port (7), you can't run a tcp server ("connection oriented") on the same port (it would generate "unable to bind master socket" error). Echo is a udp connection (most of the time), ftp is a tcp connection (connection oriented, stateless server). However sometimes, servers are designed to accept both tcp and udp requests on the same port. By the way DNS port is 42.
As far as your problem, not sure how to help there, sorry. I will give it a try, tonight...
Some thought, though:
The way the browser knows to connect to port 80 is that you are specifing the protocol http in front of the URL. If you type <a href="ftp://www.whatever.com" target="_blank">ftp://www.whatever.com</a> it will connect to an ftp port, which is 21. gopher is yet another port. So, what I don't know is if there is way to tell your browser that http is now mapped to port 17? It could be in preferences, c:\winnt\system32\drivers\etc\services file or elsewhere.
Or another way is to add a service, like say cisco://www.blah.bla would take you to port 17 if your services file has a line:
cisco 17/tcp
Like I said, all of these are just speculations at this point, but they seem to be on the right track.
Another solution is to configure your cisco server to start on port 80 instead of 17 (make sure you kill http server on that host first)
The very last (and a better idea) I have is to reconfigure your proxy configuration for http to point to cisco server on port 17. You would need some creative configuration there to be able to allow other internet connections...
Hopefully this helps...
