Although this will solicit different responces from different people based
upon their view of Windows OS, the blanket statement that it is dangerous to
use a DMZ is blatantly false.

Enterprise class corporations around the global use DMZ zones safely and
securely all the time irregardless of the OS in use, whether nix, Windows,
Sun or even MAC. If this were not true, why would Enterprise class firewalls
such as Cisco, Sonicwall, Checkpoint and others actively support DMZ zones
and there use? As it is, the best practices for an Exchange server farm
including FE/BE dictates that the FE servers are in a DMZ and the BE in the
LAN, sometimes connected using VPNs.

Likewise, domains are used in the DMZ quite frequently. IMO, it makes
administration of them easier. I do always recommend that the DMZ be in a
separate domain for security.

What it does all boil down to is the diligence and knowledge of those
responsible for the DMZ and its configuration. (Meaning from the implementer
to the policy creator to the CEO.)
