using Novell DNS and DHCP on Netware 6.5
Have Windows XP and Macintosh OS9 and OSX Clients

Both platforms are getting ip addresses via dhcp correctly
I appears only the windows clients are getting their "IN-ADDR" reverse
lookup entries updated..
we are using Dynamic DNS as well.. and only the windows clients are
causing the DNS server to create entries for them, the macintosh
computers are in fact getting good ip addresses, BUT no IN-ADDR entry is
created and no reverse lookup entry is created.

Any ideas ??
Thanks in advance
