Configuring WinPE security settings
If the server that contains your data store does not support the Microsoft NT Lan Manager (NTLM) settings for NTLMv2 Level 3, you must change the NTLM settings for the WinPE image on the TFTP server.
Before you begin
The TFTP server must have the Microsoft Windows Automated Installation Kit (WAIK) installed.
To change the NTLM settings
The ImageX command-line tool is deprecated in Windows 8. Use the DISM command-line tool.
For more information, see the following articles:
Use the imagex utility to mount the WinPE image to any empty directory. (The imagex utility comes with WAIK.)
- Open the registry editor (regedit).
- Click HKEY_LOCAL_MACHINE.
- Choose File > Load Hive.
- Select the file:
%Mounted WinPE Image folder in step1%\Windows\System32\config\SYSTEM - Enter the following key name:
WinPE_Image_SYSTEM
- Browse to: HKEY_LOCAL_MACHINE\WinPE_Image_SYSTEM\ControlSet001\Control\Lsa
- This step describes how to add an entry if the LMCompatibilityLevel value does not currently exist. If an LMCompatibilityLevel value already exists, you can edit the existing entry to match these values.
Select Edit > New> DWORD Value, and then add the following registry values:
Value Name: LMCompatibilityLevel
Data Type: REG_DWORD
Value: 3
Valid Range: 0,3 - Click HKEY_LOCAL_MACHINE\WinPE_Image_SYSTEM.
- Choose File > Unload Hive.
- Use imagex to unmount the mounted WinPE image:
imagex /unmount /commit MountFolder
