English Dates In Internet Explorer

I am writing an ASP application for Internet Explorer in the UK. I have found that some of the computers on our intranet at work display dates in Internet Explorer in English format, and some in American. However, when I look in Control Panel at the regional date settings, they are all set to English date. But IE still shows the date as American.

What is more mystifiying is that the dates in my Access database are saved correctly in the English format. It is as if Access can interpret the dates correctly when saving and retrieving, but IE and ASP cannot when performing calculations or displaying on the screen. There surely must be a way of telling IE to follow the computer regional settings when it stores dates in memory?
