Question : Does Vista have a built in DHCP server?

Does Vista have a built in DHCP server? I am trying to run a third party DHCP server and it's saying that the DHCP port used by some other application... Oh, by the way, the software is called Tftpd32 which has both the DHCP server and a tftp server, I need both... ;-)

If you know other similar software with similar functions, please let me know.
