访问远程计算机上的注册表

问题描述

我正在尝试访问远程计算机的注册表(Windows 2003).
遵循文章中的评论:

我同时使用了模拟和WNetAddConnection2.

这是我的代码:

Hi,

I am trying to access the registry of a remote computer (windows 2003).
Following the remarks in the article:
http://msdn.microsoft.com/en-us/library/ms724840(v=vs.85).aspx
I used both Impersonation and WNetAddConnection2.

Here is my code:

void ConnectRemoteRegistry(LPCSTR machine, LPWSTR wRemoteName, LPWSTR wUser, LPWSTR wPass,

LPCSTR cUser, LPCSTR cPass, std::string keyName)
{
DWORD dwRetVal;
NETRESOURCE nr;
DWORD dwFlags;

// Zero out the NETRESOURCE struct
memset(&nr, 0, sizeof (NETRESOURCE));

// Assign our values to the NETRESOURCE structure.
nr.dwType = RESOURCETYPE_ANY;
nr.lpLocalName = NULL;
nr.lpRemoteName = wRemoteName;
nr.lpProvider = NULL;

// Assign a value to the connection options
dwFlags = CONNECT_UPDATE_PROFILE;
dwRetVal = WNetAddConnection2(&nr, wPass, wUser, dwFlags);

if (dwRetVal == NO_ERROR)
    wprintf(L"Connection added to %s\n", nr.lpRemoteName);
else
    wprintf(L"WNetAddConnection2 failed with error: %u\n", dwRetVal);

HANDLE _token;

dwRetVal = LogonUserA(cUser, NULL, cPass, LOGON32_LOGON_NETWORK_CLEARTEXT, LOGON32_PROVIDER_DEFAULT,

&_token);

if(dwRetVal != ERROR_SUCCESS)
{
    wprintf(L"LogonUserA failed with error: %u\n", dwRetVal);
}

dwRetVal = ImpersonateLoggedOnUser(_token);

if(dwRetVal != ERROR_SUCCESS)
{
    wprintf(L"ImpersonateLoggedOnUser failed with error: %u\n", dwRetVal);
}

HKEY root(HKEY_LOCAL_MACHINE);
HKEY r;
LONG rc = ::RegConnectRegistryA(machine, root, &r);

if (rc != ERROR_SUCCESS)
{
    wprintf(L"RegConnectRegistryA failed with error: %u\n", dwRetVal);
}

HKEY key_handle;

rc = ::RegOpenKeyExA(r,keyName.c_str(), REG_OPTION_OPEN_LINK,
KEY_QUERY_VALUE, & key_handle);

if (rc != ERROR_SUCCESS)
{
    wprintf(L"RegOpenKeyExA failed with error: %u\n", dwRetVal);
}

RegCloseKey(r);
RevertToSelf();

dwRetVal = WNetCancelConnection2(nr.lpRemoteName, CONNECT_UPDATE_PROFILE, true);

if (dwRetVal != NO_ERROR)
    wprintf(L"WNetCancelConnection2 failed with error: %u\n", dwRetVal);
}

我正在使用远程计算机的本地管理员.
WNetAddConnection2到c $已成功完成.
LogonUserA和ImpersonateLoggedOnUser已成功完成.
RegConnectRegistryA也已成功完成.
问题是RegOpenKeyExA返回5-访问被拒绝.

您能告诉我为什么会这样吗?

谢谢.

I am using a local administrator of the remote machine.
WNetAddConnection2 to c$ is completed successfully.
LogonUserA and ImpersonateLoggedOnUser are completed successfully.
RegConnectRegistryA is also completed successfully.
The problem is that RegOpenKeyExA returns 5 - access denied.

Can you please advise why that might be?

Thanks.

推荐答案

ulOptions
[in] Reserved; set to 0.
