Question : TFTP Timeout

I have installed the Windows Deployment Server, but when i m booting from the Network it is showing the error TFTP Timeout and was stopped there.
DHCP was giving the IP Address but not booting further.

Answer : TFTP Timeout

You can restart wds service. If it doesn't help, you may try to unconfigure / configure again.
This is not the solution but may help.

Are you sure there's no firewall issues?
