我需要能够在远程计算机上运行RegLoadKey(),可能是我的计算机和远程计算机不在同一个域中。如果是,则以下代码可以正常工作,我可以冒充在该计算机上具有管理员权限的用户。否则,如果我们谈论本地用户,根据这个讨论,我发现......

...我的机器上必须有一个本地用户,用户名和密码相同。啊。有办法吗?
using System.Runtime.InteropServices;
using System.Security.Principal;
[DllImport("advapi32.dll")]
public static extern int LogonUserA(String lpszUserName, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern int DuplicateToken(IntPtr hToken, int impersonationLevel, ref IntPtr hNewToken);
[DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool RevertToSelf();
[DllImport("kernel32.dll", CharSet = CharSet.Auto)]
public static extern bool CloseHandle(IntPtr handle);
public const int LOGON32_LOGON_INTERACTIVE = 2;
public const int LOGON32_PROVIDER_DEFAULT = 0;
public WindowsImpersonationContext WearDrag(string Username, string Password, string DomainOrMachine)
{
WindowsImpersonationContext impersonationContext;
WindowsIdentity tempWindowsIdentity;
IntPtr token = IntPtr.Zero;
IntPtr tokenDuplicate = IntPtr.Zero;
if (RevertToSelf())
{
if (LogonUserA(Username, DomainOrMachine, Password,
LOGON32_LOGON_INTERACTIVE,
LOGON32_PROVIDER_DEFAULT, ref token) != 0)
{
if (DuplicateToken(token, 2, ref tokenDuplicate) != 0)
{
tempWindowsIdentity = new WindowsIdentity(tokenDuplicate);
impersonationContext = tempWindowsIdentity.Impersonate();
if (impersonationContext != null)
{
CloseHandle(token);
CloseHandle(tokenDuplicate);
return impersonationContext;
}
}
}
}
if (token != IntPtr.Zero)
CloseHandle(token);
if (tokenDuplicate != IntPtr.Zero)
CloseHandle(tokenDuplicate);
return null;
}
答案 0 :(得分:10)
以下是我一直在使用的内容,而无需定义本地用户:
const int LOGON32_LOGON_NEW_CREDENTIALS = 9;
const int LOGON32_PROVIDER_DEFAULT = 0;
bool isSuccess = LogonUser(username, domain, password,
LOGON32_LOGON_NEW_CREDENTIALS,
LOGON32_PROVIDER_DEFAULT, ref token);
之后:
WindowsIdentity newIdentity = new WindowsIdentity(token);
WindowsImpersonationContext impersonatedUser = newIdentity.Impersonate();
我不会复制句柄。
另一个观察 - 我不使用LogonUserA,我只是使用LogonUser。
