More information is certainly needed;

a: Can the target server be isolated from other hosts? Extranet
b: Will this server have a separated Active Directory server?
c: What applications are needed by external users?
d: What applications are needed by internal users (admins)?
e: Can the MS host administrators manage the separation of these different users?
f: Is this just the only host, or are there more to come?
g: Do you have a VPN? Maybe this is the time to propose one.
h: Does someone have the responsibility to review Event log files on this host?

There is a ASP that offers its custom application via Terminal Services to businesses
across the Internet. No special IPs are blocked, but most ports are blocked. But more
importantly the systems are very much hardened, and account management is
very tightly controlled, and user access to any host application is restricted. It works
but it takes both network security and host security to work together to keep it
working.

My comfort level was not that high.
