The inconsistency between these two points might actually lead the OP to a solution. Evidently Vista does something different with the DHCP broadcast flag, see: http://support.microsoft.com/kb/928233 If you specify a network and netmask in the subnet statement, you shouldn't need to override the broadcast address it computes, which for the config posted ought to be "192.168.2.255". Using the all-ones broadcast address should not be done by normal members of the network-- only for things which need to go beyond the network subnet/ topology (ie, the DHCP server itself might choose to send to 255.255.255.255 to make sure that anything else on the local collision domain sees it, even if the local network is split into multiple logical subnets).
