I just *had* to comment.

Well, I have.  Note that he said "exclusive of help-desk activities".
Keeping Windows up-to-date can be accomplished by a number of things,
including their auto-update feature, SMS, and even remote desktop.  And much
of that can be dealt with by the help desk.

It may be - but there's only been one unnamed) example mentioned so far.
Considering the number of production environments out there, this does not
seem to move it beyond the "special case" category.  If you're mentioning
others, then that might change.

It depends upon 1) how you classify help-desk work, and 2) whether or not
you're categorising back-end and front-end work differently.  If you do,
then the number of clients is most relevant for load testing.
