Actualy, scratch the first question. No we don't have an -r option in use b/c we are using another tftp binary (tftpd) which probably doesnt even support option negotiation. So does the tftp-hpa binary work on bsd os versions?

Everything has worked well up to this point, however I've been trying to impliment a pxe bartpe solution in our office. Unfortunatly tftp is not passing the files correctly to the client.

The next step is where the client will call NTLDR from the tftp server, this works fine and the client begins to load NTLDR. However NTLDR calls a file called ntdetect.com from the server. The server ACK's the call and then ends up failing.

Looks like you have configured tftp-hpa to reject the blksize option (-r
blksize) and NTLDR doesn't like that.
