I am goin to try and be brief. I purchased a new laptop with windows vista installed. I have been accessing a college website from my desktop pc that has windows xp installed and have no problems. For convenience purposes I purchased a laptop and it has vista installed. Now my problem is that when trying to log in to my college website from my laptop it keeps telling me that it is an invalid login id. Tried putting in my student number and tells me I don't exist. Thought it might have been a problem with the website but went to my desktop pc with xp installed and logged in the website with no problems..Could there be something I am missing is it a vista problem and if so how do I fix it.

Do you require Office installed to access the website? Have you cleared out any cookies and cached forms and passwords?
Also, in Internet Options, Security, Custom, change the the login to Prompt for user and password.
