Windows 2000 Training recommendation

I was wondering if anyone could recommend a good Windows 2000 training class? I am looking for a Windows 2000 course that covers both (Server/Advanced Server) perspective as well as the client side (Win 2k Pro). I am obviously looking for this course to be Online, reliable, and designated for I.T. professionals. The Plan is for my employer to pay for such an online course, as well as future courses for myself and other co-workers.

Thank you for any suggestions you may be able to send myway!
