Step-by-Step Guide: How to repair Exchange-related IIS virtual directories

The original is on archive.org.

 This article was the best, easiest, and to the point fix for a corrupted Exchange
IIS Virtual directories.  I spent hours trying to track this issue down. 
It seems that the secret was to enter in the correct search terminology in Google. 
I was using words like reinstall, fix, OWA, Outlook Web Access, etc.  At the
last minute I used “repair outlook web access 2003” and the second search result was
it.  The website requires that you register, for free, and go through a whole
series of questions.  It was well worth it in the long run.

Brien Posey was the guy who wrote the
article.  His picture made him look like a twenty something but his resume was
rockin’.  I will definitely use any of his technical articles.
