Question

我正在编写一个用于操作Windows服务的应用程序。我的电脑在工作组中。但我无法访问机器。我已经使用LogonUser（）尝试了模拟。但是没有用。我可以使用远程桌面连接进行操作，但我无法以编程方式访问。

    ImpersonateUser ImpersonatedUser = new ImpersonateUser();
    ImpersonatedUser.Impersonate(Domain, Username, password);
    ServiceController sc = new ServiceController("servicename", host_name);
    Console.WriteLine("Success."); 


  //impersonation.
public class ImpersonateUser
{
    [DllImport("advapi32.dll", SetLastError = true)]
    public static extern bool LogonUser(
    String lpszUsername,
    String lpszDomain,
    String lpszPassword,
    int dwLogonType,
    int dwLogonProvider,
    ref IntPtr phToken);
    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
    public extern static bool CloseHandle(IntPtr handle);
    private static IntPtr tokenHandle = new IntPtr(0);
    private static WindowsImpersonationContext impersonatedUser;
    // If you incorporate this code into a DLL, be sure to demand that it
    // runs with FullTrust.
    [PermissionSetAttribute(SecurityAction.Demand, Name = "FullTrust")]
    public void Impersonate(string domainName, string userName, string password)
    {
        //try
        {
            // Use the unmanaged LogonUser function to get the user token for
            // the specified user, domain, and password.
            const int LOGON32_PROVIDER_DEFAULT = 0;
            // Passing this parameter causes LogonUser to create a primary token.
            const int LOGON32_LOGON_INTERACTIVE = 2;
            tokenHandle = IntPtr.Zero;
            // ---- Step - 1
            // Call LogonUser to obtain a handle to an access token.
            bool returnValue = LogonUser(
            userName,
            domainName,
            password,
            LOGON32_LOGON_INTERACTIVE,
            LOGON32_PROVIDER_DEFAULT,
            ref tokenHandle); // tokenHandle - new security token
            if (false == returnValue)
            {
                int ret = Marshal.GetLastWin32Error();
                throw new System.ComponentModel.Win32Exception(ret);
            }
            // ---- Step - 2
            WindowsIdentity newId = new WindowsIdentity(tokenHandle);
            // ---- Step - 3
            {
                impersonatedUser = newId.Impersonate();
            }
        }
    }
    // Stops impersonation
    public void Undo()
    {
        impersonatedUser.Undo();
        // Free the tokens.
        if (tokenHandle != IntPtr.Zero)
        {
            CloseHandle(tokenHandle);
        }
    }
}

我发现我们无法在工作组计算机上冒充用户。虽然我们冒充，但WorkGrooup计算机强迫用户成为访客。因此，如果我们想以用户身份登录，我们需要更改注册表值forceguest = 0

如何远程访问工作组计算机中远程主机的Windows服务？
