TFTP: File Not Found

[Scott B]

With a lot of help from @Sebastian-Roth we did track down the issue. Someone must have been in our DHCP server and changed the case of the undionly.kpxe to all caps… thus not finding the file. Sometimes is those simple things you just don’t think to look for. Thanks again for your help Sebastian!

You are welcome! As well I learned to pay even more attention to what I see in the PCAP file. Would have saved us at least an hour or two… When testing with the command line client Scott didn’t know about the important -i option for Windows tftp command line client as described here. When looking at the PCAP file Scott sent me I didn’t notice that it tried to request the file in ‘netascii’ mode instead of ‘binary’.

So everything is working now and it was just the upper case filename option in the DHCP config…
