SO... I have to flood my network with broadcast traffic or pay the microsoft extortion...

That I can't find a setting for.I have no Vista clients to test with, but have you tried "always-broadcast on;" ?From "man dhcpd.conf" on CentOS 5.2: always-broadcast flag; The DHCP and BOOTP protocols both require DHCP and BOOTP clients to set the broadcast bit in the flags field of the BOOTP message header. Unfortunately, some DHCP and BOOTP clients do not do this, and therefore may not receive responses from the DHCP server. The DHCP server can be made to always broadcast its responses to clients by setting this flag to 'on' for the relevant scope; relevant scopes would be inside a conditional statement, as a parameter for a class, or as a parameter for a host declaration. To avoid creating excess broadcast traffic on your network, we recommend that you restrict the use of this option to as few clients as possible. For example, the Microsoft DHCP client is known not to have this problem, as are the OpenTransport and ISC DHCP clients.
Thanks for that. I had been reading the dhcp man page (I should say book! What a long one.) I guess I missed that. I'll have to set any Vista clients to named hosts so I can limit the traffic.
According to that man page, ISC implies that Vista is broken, and Microsoft implies that ISC is broken. Were playing the blame game again!
How fun! ;-P And I thought it was going to get boring... -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!!
