Web page error 404

[jgombert]

Hello

The Problem i am having is that our website is hosted by a hosting company, when ever we try and browse the website from our network from internet explorer/firefox, the front page of the website displays properly , but all other links on the website cause the following error :" Error 404 The requested URL was not found on this server. Apache /2.059(Netware) Mod_jk/1.2.15 "

I can't seem to see why this is happening. Any help will be appreciated

We are running Netware 6.5 sp6
Thanks
