File open dialog on a domain joined machine

In this article Marc Russinovich explains into Detail (may be too much) why it takes longer to open a file dialog on a domain joined machine that has no connection to the domain at the present time. The sessions he talks about in this post I have seen. They were great indeed. It is something to think about when you use your laptop for live demo’s because waiting for 5 to 15 seconds every time you try to open a file may be very annoying and frustrating for the audience.
