PXE-E32: TFTP open timeout

When I trying to boot from LAN on Hyper-V machine I got "PXE-E32: TFTP open timeout"

To solve this issue:

1- Ensure that WDS is running
2- Add option 066 to DHCP server and set this option's value to the IP address or host name of WDS server
3- Add option 067 to DHCP server and set this option's value to: boot\x86\wdsnbp.com

if still got this error go to your WDS server

1- Run regedit
2- Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\WDSServer\Parameters
3- Double click UdpPortPolicy and set value = 0
4- Restart the Windows Deployment Services service

if you still got this error

1- Open your WDS console
2- Right-click the server, and then click Properties
3- Click Network, increase the UDP Port range to 4000 ports.

Now you must be able to boot from LAN

NOTE:
If you are using Hyper-V you must add Legacy Network Adapter to your virtual machine hardware.
