Errors in TFTP download of boot image from PXE server.
Multiple possible causes
1) Check the TFTP service on the server that is supposed to be servicing the TFTP request
a. An easy way to determine if the MTFTP service is up and also confirm the IP address it is listening on would be to use the command netstat –an on the PXE server at a command prompt and look for UDP 10.20.30.40:69 in the return. Replace the IP address with the IP Address of the server being tested.
b. Another good test to be performed, should be performed from the segment where the PXE client is attempting to be booted. Use the TFTP command line utility available at http://www.tftp-server.com/tftp-client.html to attempt a download of the bstrap.0 file from the MTFTP service.
c. Download tftp.exe from the URL above, to c:\
d. Run the following command c:\tftp.exe -i 10.20.30.40 get BStrap\X86pc\BStrap.0 c:\test.txt and review the result. Replace the IP address with the IP Address of the server being tested.
Note: The result should come back as something similar to the following if MTFTP is up and end to end connectivity to tftp is available.
