在Windows XP上,有一种已知的方法可以创建远程协助票证。

但在Vista上,这似乎不起作用。如何在Vista或Windows 7上执行此操作?

原来有两种方式。 Microsoft API称为IRASrv,并在此处记录:

另一种方法是简单地调用msra.exe。使用密码和新手参数(例如msra.exe / saveasfile testfile thepassword)。但是,这会使用密码对话框提示用户。
以下是调用IRASrv接口并生成远程协助连接字符串的示例代码。
COSERVERINFO si; ::ZeroMemory( &si, sizeof( si ) );
MULTI_QI qi; ::ZeroMemory( &qi, sizeof( qi ) );
HRESULT hr = S_OK;
BSTR bstrUserName = SysAllocString(L"jon");
BSTR bstrDomainName = SysAllocString(L"");
BSTR bstrPasswordStr = SysAllocString(L"testpass");
// Get the security information entered by the user
_bstr_t bstrUser(bstrUserName);
_bstr_t bstrDomain(bstrDomainName);
_bstr_t bstrPassword(bstrPasswordStr);
// Set AuthIdentity
SEC_WINNT_AUTH_IDENTITY_W AuthIdentity = {
(unsigned short*)bstrUserName,
bstrUser.length(),
(unsigned short*)bstrDomainName,
bstrDomain.length(),
(unsigned short*)bstrPasswordStr,
bstrPassword.length(),
SEC_WINNT_AUTH_IDENTITY_UNICODE
};
COAUTHINFO AuthInfo = {
RPC_C_AUTHN_WINNT,
RPC_C_AUTHZ_DEFAULT,
NULL,
RPC_C_AUTHN_LEVEL_PKT_PRIVACY, // The authentication level used
RPC_C_IMP_LEVEL_IMPERSONATE,
(COAUTHIDENTITY*)&AuthIdentity,
EOAC_NONE
};
si.pAuthInfo = &AuthInfo;
si.pwszName = bstrMachineName;
qi.pIID = &(__uuidof(RAServerLib::IRASrv));
hr = ::CoCreateInstanceEx(
__uuidof(RAServerLib::RASrv), NULL, CLSCTX_REMOTE_SERVER,
&si, 1, &qi );
if (FAILED(hr))
{
return hr;
}
CComPtr<RAServerLib::IRASrv> prasrv;
hr = qi.pItf->QueryInterface(__uuidof(RAServerLib::IRASrv), (void**)&prasrv);
if (FAILED(hr))
{
return hr;
}
LPWSTR pstr=NULL;
hr = prasrv->raw_GetNoviceUserInfo(&pstr);
if (FAILED(hr))
{
return hr;
}
pstr contains the Remote Assistance Connection String (type 2)
