By-pass the Logon Page

Is it possible to by-pass the logon page? Either by way of using the active directory authentication option or using a generic logon account for all users BUT the tech's and admin account?

Our concern is that we do not want users to have to logon to place a service request. I understand there is the option to 'remember password' but even that is enough to make our users shy away from this tool (we are an agriculture company, ie. farmers and old people - so that may help you understand the mindset somewhat).

Ideally there would be a way to link directly to the request form page for regular users and the tech's can connect as normal and use the remember password option.

Please let me know what options are available.

Thanks
