There is a way to set more than 6 IP addresses (the main one, and 5 more)
for an NT server, however, it requires the use REGEDT32...

Also, the keys escape me at this point (although I'll check in the
registry).

Another good place to post this is in the NT Server section of
msnews.microsoft.com, where MS personnel and other users monitor and answer
questions such as these.  (Be prepared to get the disclaimer that "it's not
supported" - although it *can* be done.
