3. Make a Batch Script

In order to resolve network boot issues brought on by duplicate addresses, this batch script requires your system to release and renew the IP address as well as reset the TCP/IP stack.

• Copy and paste the following commands into Notepad.
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpServer /freg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpIPAddress /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpSubnetMask /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpSubnetMaskOpt /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpServer /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpIPAddress /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpSubnetMask /f
  reg delete HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces\{6B367847-567F-4C19-B42E-EF27899A1F9D} /v DhcpSubnetMaskOpt /f

• Replace {6B367847-567F-4C19-B42E-EF27899A1F9D} with the correct GUID for their network adapter, which can be found using tools like ‘ipconfig /all’ or ‘netsh’, and ensure that you back up your registry before making any changes.
• Go to “File” and choose “Save As”.

• Enter “script.bat” as the file name and select “All files” for the save type.
• Finally, configure the script to run in read/write mode on the virtual disk before shutdown.

4. Make a Script for the Registry Editor

If you’re comfortable with the Windows Registry, you can create a custom script to modify network boot parameters and resolve the root cause of the duplicate address error.

• Copy and paste the following into Notepad:
  Windows Registry Editor Version 5.00
  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
  “NameServer”=””
  [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces][HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID_OF_NETWORK_ADAPTOR}]
  “NameServer”=””
  “Domain”=””
  “DhcpIPAddress”=””
  “DhcpSubnetMask”=””
  “DhcpServer”=””
  “DhcpNameServer”=””
  “DhcpDefaultGateway”=””

• After selecting “File”, click “Save as”. Name the file “reset.reg” and select “All files” as the save as type.

• Next, reopen “Notepad” and copy the following commands:
  net stop DHCP
  a /s reset.reg
• The file should be saved as “script.bat”.

• Finally, program it to operate during the shutdown procedure.
