I've been in those shoes myself, and recommed you may want to keep the
IP based authorization until you can get a better AD system.

Yes they all still support Basic, but you said that was not desirable.
The secure methods that leaves you with are NTLMv2 (definitely *not*
NTLMv1) or Negotiate/Kerberos.
NTLM was deprecated by MS in 2006. All software produced by MS since
then is increasingly hostile to NTLM being used and preferring Kerberos.
XP can handle Kerberos with maybe a little config. And it is both more
secure and faster so a double-win once you get over the learning curve
for its management tools.
I'm not sure if or how the Win2k server can handle Kerberos. You will
need to find that out.
