DHCP- and TFTP-Server configuration (http://thinstation.sourceforge.net/faq.html#7)
The MS Windows servers come with a build-in TFTP server called "Remote Installation Service". However, it needs a domain controller to work, unless you use a hack (http://www.simonsen.bz/w2k_standalone_tftp_dameon.htm) by Morgan Simonsen (mind you - you still need a valid MS Windows server licens).

An other possibility to get a small and simple combined DHCP and TFTP server for MS Windows is http://tftpd32.jounin.net/ (supports "tsize" for PXE boot). To run it automatically as a service, use FireDaemon (http://www.firedaemon.com) (free for non-commercial purposes).
Check out Zack Forsyth's excellent guide Running a non-RIS TFTP server as a service in MS Windows server (http://thinstation.sourceforge.net/tftpd-service.html) concerning this.

小而美是一種美德, tftpd32 已經夠小的了, PumpKIN 竟然比它還小, 不過那是有原因的, 因為tftpd32 多了DHCP/SNTP/Syslog Server, 如果你只需要tftp client/server 的話, 那麼PumpKIN 應該是可以勝任愉快的
