Ian, this course is so ancient that you can't find the files for it's lab anywhere. Not in MOCL, not anywhere else. I suggest you start teaching something newer than .NET 1.1 concepts - there are courses on 3.5 and 4.0, for instance. 10266A, for example.
Besides, you may ask for it in MCT groups in LinkedIn, but I doubt anyone still have that, even if these files were ever released. I am not sure this course had any labs at all.
