Hmm, that's weird that the link didn't work. But I guess that isn't the first time I've seen it happen. I would just try again, I just downloaded the zip and it was right.
Here is the direct link to the ISO for burning a CD with:
http://home.eunet.no/~pnordahl/ntpasswd/cd060213.zip
And here is the floppy image creator:
http://home.eunet.no/~pnordahl/ntpasswd/bd050303.zip
See if they work now. For the CD, unzip and you will get a single ISO file. Burn this to CD using your burning program like Nero or EZCD Creator. There is a few files in the floppy image, double-click the executable and it should write the files to a floppy disk.
You MUST read the site on how to use the program, should you get it to work! It can sometimes look daunting, because of all the text and command line garbage, but it's really not that hard, as most (correct) options are automatically chosen.
Next, you can't change the pass from the control panel, but did the commands I gave you work at all? Again, click Start and Run. Then try either
control userpasswords2 or
control userpasswords.
This probably would only work from a user with admin privileges anyway.
If you DO have admin privileges, you can probably check your own policies and change them yourself. In regedit, you can go to both:
HKCU\Software\Microsoft\Windows\CurrentVersion\Policies
and
HKLM\Software\Microsoft\Windows\CurrentVersion\Policies
If you just browse those keys and subkeys, and look at the values on the right side, some policies are quite obvious. Such as "AllowRun" or "DesktopProperties" or similar, whatever. If they are set, then those are blocked. If you delete the policy entry, and then log off and on again, you will be free from it.
Anyway, to much info for now. Try the run commands again, and try that program again. Oh, and 2000 doesn't have a built-in wireless program. You'll have to use the one from the manufacturer.
Good luck
