bind vs. MS DNS

[huffman at graze.net]

All,

   Don't want to start any nasty feuds, but can anyone point me to pros / cons
of using bind in favor of MS DNS?  My company is currently looking at migrating
from a UNIX / Bind DNS scenario to MS DNS / Active Directory.  I feel that the
maturity, security, and stability of bind on UNIX are big wins, but currently
we're not hosting our own DNS externally, so security is *less* of a concern and
we're small so things like views, and scalability are also not concerns....

Pointers to any articles would also be helpful.

Thanks!
Brian
