TFTP and RIS for Windows Installation (Broadcast ACK Problem)

[Chris]

I'm having trouble setting up a RIS server for windows.  I'm following 
the instructions from http://oss.netfarm.it/guides/ris-linux.php except 
I'm trying to use freebsd's native tftp.  I used Wireshark and the 
problem appears to be that Freebsd TFTP doesn't recognize broadcast 
ACK's from the client while transfering a file.  TFTP works for sending 
the bootrom image since the PXE uses an actual IP address for the 
request but retrieving XPLDR fails because the bootrom code only uses 
broadcasts.  TFTP seems to start the transfer but it never seems to 
register the broadcast ACK and tries to resend the same packet.

I'm going to try other tftp servers but I thought I'd do a post to see 
if anyone else has experienced this.
