-------------------------------------------------------Hi Jim,

I am only repeating what I was told when Mike Nash, Paco Cruz and Steven Ashby 
from Microsoft's Technet group flew down and met with the board of my user 
group, the NTEA of which I was the Vice President and Postmaster www.ntea.net. 
We used an Imail list server and Fatbrain hosted the meeting shortly after they 
were acquired by Barnes and Noble . During that visit the team mentioned then 
that all the content posted to the Technet web site and on the technet CD's 
were maintained by a small group, of course this was in late 2000 and Mike Nash 
has since moved into the security role, and things may have changed.

I worked for Cisco, IBM, LSI Logic and I can't tell you everything their 
products do. Of course I realize that you are an Exchange & ISA expert, but how 
many Production Clusters have you built in a large Enterprise such as Microsoft?

Let me go back to my MOC on Clustering to verify the netbios recommendation in 
the course ware, it's been several years.

Peace,

Jose
