If you’ve just installed a brand new installation of Windows Deployment Services, but your PXEboot isn’t working properly, then the fix is to disable NetBIOS over TCP/IP.

These are the kinds of issues this will fix:

PXEBoot not kicking in at all
PXE-E55 Proxy DHCP Service did not reply to request on port 4011.
TFTP errors, retrying over and over again

Here are some more detailed instructions if needed:

1. Open Control Panel
2. Click Network and Sharing Center

 

 

 

 

 

 

 

 

 

 

3. Click on the Ethernet connection

 

 

 

 

 

 

 

 

 

 

 

 

4. Click Properties

 

 

 

 

 

 

 

 

 

 

 

 

 

5. Double-click Internet Protocol Version 4 (TCP/IPv4)

 

 

 

 

 

 

 

 

 

 

 

 

 

6. Click Advanced …

 

 

 

 

 

 

 

 

 

 

 

 

 

 

7. Click the WINS tab

 

 

 

 

 

 

 

 

 

 

 

 

 

8. Click “Disable NetBIOS over TCP/IP”

9. Click OK then OK again

Reboot your workstations and you’ll see the network PXE Boot kick in really quickly and consistently.
