LAN Manager - Windows 7

In windows 7 you may encounter problems in accessing network resources because of default "LAN Manager authentication level" group policy setting.

To modify this setting navigate to:
Local Computer Policy - Computer Configuration - Windows Settings - Security Settings - Local Policies - Security Options - LAN Manager authentication level

  1. I'm looking for a way to change this setting using Powershell. Any ideas?

    1. shure it is: there is a registry key that this policy is changing and powershell can work with registry;

      key location is: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Lsa]

      key name is "LmCompatibilityLevel" (DWORD) and is set to "1"
