I don't think the question is whether or not this guy has MCP status.  

If you're a VB6/MSSQL 7- shop, then give him a VB6/MSSQL 7- technical test.   If you're not a VB6/MSSQL 7- shop, then don't bother calling him back.

Apparently the old chap wants to go the way of the dinosaur.   If he hasn't learned that software development is for the career learner then maybe he doesn't belong in the industry or maybe he likes spending most of his time maintaining legacy systems.  I've been doing this for over ten years so I like to work the cutting edge and leave the grunt work to juniors.
