The people at Webucator were kind enough to make a video based on my article on dealing with SQL Server Lock Resource Errors. While I am certainly biased, I think the video came out quite well. They also have a series of courses on SQL Server available here and their YouTube page with other videos is here.
Additionally, MSSQLTips has published another piece of mine dealing with Programmatically Changing SQL Server Linked Tables in Microsoft Access.
