I had a call from a person, who shall remain nameless, who had a question about sub-domains on IIS, specifically how to using Host Headers to host multiple websites on IIS 6.0.
I didn't know the answer off the top of my head.
He checked the MSDN Managed newsgroups, specifically microsoft.public.inetserver.iis where he just found the answer in the first few posts.

This post is a stark reminder to us all. If you want an answer to a question, don't call me!
