I think you will need to tell dhclient to send the hostname to the DHCP 
server.  (I assume the DHCP server on Windows is automatically updating 
the DNS server, correct?).  According to dhclient.conf(8), you do this by 
placing something like this within the interface{} stanza:
	host-name "andare.fugue.com";

I think that you can also specify the hostname in the DHCP settings 
through redhat-config-network, and that should generate the appropriate 
setting above.  Keep in mind that if you do edit dhclient.conf manually, 
it might be overwritten by such utilities if you run them later.

Hope this helps,
