如何用PowerShell自动化配置Windows高级共享的所有网络设置？

1. Yes, PowerShell scripts exist for these settings #

All three "All Networks" sharing settings can be configured by modifying Windows Registry keys via PowerShell. Below are the scripts for each requirement, plus guidance on applying them and integrating with your C# program.

2. Step-by-Step Configuration Scripts #

All commands must be run as Administrator to modify system-level registry keys and services.

2.1 Enable Public Folder Sharing (Read/Write for All Network Users) #

This setting grants full read/write access to Windows Public folders for any network visitor:

# Set Public folder sharing to read/write mode
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Sharing\Public" -Name "Value" -Value 2

# Enable automatic sharing of Public folders
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" -Name "AutoShareWks" -Value 1

2.2 Enable File Sharing for 40/56-bit Encryption Devices #

This allows older devices using weaker encryption standards to connect to your file shares:

# Set minimum encryption level to support 40/56-bit devices
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" -Name "MinEncryptionLevel" -Value 1

2.3 Turn Off Password-Protected Sharing #

This removes the requirement for network users to enter a Windows account password to access shared resources:

# Disable password-protected sharing
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network" -Name "DisablePasswordProtectedSharing" -Value 1

2.4 Apply Changes Immediately #

Restart the Server service to activate the new settings without a full system reboot:

Restart-Service -Name LanmanServer -Force

3. Full Combined Script #

Here's a complete script that handles all three settings and applies changes in one go:

# Require Administrator privileges to run
#Requires -RunAsAdministrator

# 1. Configure Public Folder Sharing (Read/Write)
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Sharing\Public" -Name "Value" -Value 2 -ErrorAction Stop
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" -Name "AutoShareWks" -Value 1 -ErrorAction Stop

# 2. Enable 40/56-bit Encryption Support
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" -Name "MinEncryptionLevel" -Value 1 -ErrorAction Stop

# 3. Disable Password-Protected Sharing
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network" -Name "DisablePasswordProtectedSharing" -Value 1 -ErrorAction Stop

# Restart service to apply changes
Restart-Service -Name LanmanServer -Force -ErrorAction Stop

Write-Host "All network sharing settings configured successfully!" -ForegroundColor Green

4. Integrate with Your C# Program #

To run this script from your C# application, use the System.Management.Automation namespace. Follow these steps:

1. Add the NuGet package System.Management.Automation to your project.
2. Use this code snippet to execute the script:

using System.Management.Automation;

public void ConfigureNetworkSharingSettings()
{
    string powerShellScript = @"
        #Requires -RunAsAdministrator
        Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Sharing\Public' -Name 'Value' -Value 2 -ErrorAction Stop
        Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters' -Name 'AutoShareWks' -Value 1 -ErrorAction Stop
        Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters' -Name 'MinEncryptionLevel' -Value 1 -ErrorAction Stop
        Set-ItemProperty -Path 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network' -Name 'DisablePasswordProtectedSharing' -Value 1 -ErrorAction Stop
        Restart-Service -Name LanmanServer -Force -ErrorAction Stop
    ";

    using (PowerShell psInstance = PowerShell.Create())
    {
        psInstance.AddScript(powerShellScript);
        try
        {
            var executionResults = psInstance.Invoke();
            if (psInstance.HadErrors)
            {
                foreach (var errorRecord in psInstance.Streams.Error)
                {
                    // Log or display error details
                    Console.WriteLine($"Configuration Error: {errorRecord.ToString()}");
                }
            }
            else
            {
                Console.WriteLine("Network sharing settings applied successfully.");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Execution Exception: {ex.Message}");
        }
    }
}

Key Notes #

• Your C# application must run as Administrator to modify system registry keys and restart services.
• Test the script on a non-production device first to confirm behavior matches your requirements.
• In rare cases, a system reboot may be needed if service restart doesn't apply changes (though the script avoids this where possible).
