ASP.NET Website Memory Usage quite high

Question

I have an ASP.NET website that will hit about 2gb physical memory used within about 3-4 days, which to me sounds really bad. At the moment, I have configured IIS to restart

Memory leaks in .NET are still possible. It is true that for the most part you don't need to free objects (there are a few exceptions such as the Graphics object) but if you keep references to them, they will not get garbage collected, because they are still referenced.

If the GC sees that an object is being referenced somewhere, anywhere in your app, it will not trash it.
