Such as the url of the logon page, if you can access other pages on that site, and if you can logon to cnet (for example) on that computer. It really depends on how the site asks it password. Could need javascript, java, https/ssl, activex, cookie support to name things that could be wrong in principle. But 'page not found' message is rather strange with all these things.
Then there could be site blocking by a hosts file, an ad blocker, a pop up blocker, parental control, spybot immunization, real-time spyware blocking (like MS anti-spyware beta). That most likely would explain the error message.
Did you already try another browser like Firefox. If that works, it's a very useful workaround, and it somewhat restricts the area to look for the solution.
Can you ping the site?
I don't expect it's the router. But it's free to switch connections, of course.

I have a Dell 4550 on which my hard drive crashed and I had to replace/reinstall hooked up to a linksys befw11s4 router(firmware upgraded. I have site which when you get to it requires password etc. On other computers hooked to same router I can access site but the Dell with Win Xp reinstall/updated/sp2 will not load page. I keep getting a"page cannot be foud" hhtp 404.
Any suggestions would be appreciated.
Thanks
