What's serving DHCP, the linksys router/hub or the linux router - or are these on seperate networks? They are two separate networks in two different places. One uses the

It is the dhcp server for the local net which is all windows stuff 98 and XP. The 98 machines request and get a consistent IPs assigned and work fine. It's the XP machine that has a hard time getting the IP and often defaults to the blackhole number. That same XP machine when plugged into my separate linux router never fails to get its IP assigned by the dhcp server. At the second location I have the wired stuff going into a linux router/server and it feeds into my wireless (Belkin) route which then goes to the cable modem. I know it's a little strange but I did it that way cause I had VoIP /dmz set up on the linux machine to handle my phone system independently. The wireless was added to primarily take care of laptops. Again, linux based wireless gets the IP without fail while the same laptop running XP will often come up with blackhole number and only rebooting will let it connect with the proper IP - sometimes. I have another laptop running win98 which always gets the proper IP.
Basically, a DHCP client sends out a broadcast asking for an IP, the DHCP server responds with a broadcast that the machine should get, and then the machine sends another message to the DHCP server (Ack! my Address! - or something like that :)).
So, perhaps the broadcasts aren't being passed around properly, or perhaps you've just got a bad cable - does the setup work better under Linux v/s windows when using the exact same ethernet cable in the exact same port on the exact same hub? Yes! I put linux on the hp laptop and it gets the IP right every time! Using same everything only the router is different and the linux hookup is also without a problem!
I wonder what diagnostic tool will tell me what is happening with the windows stuff. Richard
