I'm just using the one straight from the zip that Fohdeesha made and pointing it to the correct folder replacing the ip address in the instructions with my tftp server ip address. Tested it on a second windows pc and had the same issue where it opens up the file transfer window 4 times and then times out on each of them after not transferring anything.
When I enter that netstat command I get:
UDP 0.0.0.0:69 *:*
....never mind, I was in the middle of getting ready to send this reply and I found that I either needed to select something other than the local (127) server interface in the tftpd64 app or I needed to use a different ip address than I was previously using for the switch because it just worked.




Thanks for your quick response!
