Hi
I try to get info from remote host via WMI, local and remote host are
Windows 2000. Everything seemed fine and I can read the data from remote
objects. But only at the last: call pSvc->Release(), it causing 0x80070005
every time.
Here is my code:
HRESULT WMIInterfaceInit(CString strLocalUser, CString strLocalPassword,
CString strLocalWorkgroug)
{
HRESULT hres;
// Step 1: --------------------------------------------------
// Initialize COM. ------------------------------------------
hres = CoInitializeEx(0, COINIT_MULTITHREADED);
if (FAILED(hres))
{
cout << "Failed to initialize COM library. Error code = 0x"
<< hex << hres << endl;
return hres; // Program has failed.
}
// Step 2: --------------------------------------------------
// Set general COM security levels --------------------------
// Note: If you are using Windows 2000, you need to specify -
// the default authentication credentials for a user by using
// a SOLE_AUTHENTICATION_LIST structure in the pAuthList ----
// parameter of CoInitializeSecurity ------------------------
// Auth Identity structure
SEC_WINNT_AUTH_IDENTITY_W authidentity;
SecureZeroMemory( &authidentity, sizeof(authidentity) );
authidentity.User = (unsigned short*)strLocalUser.LockBuffer();
authidentity.UserLength = wcslen( (WCHAR*)(authidentity.User) );
authidentity.Domain = (unsigned short*)strLocalWorkgroug.LockBuffer();
authidentity.DomainLength = wcslen( (WCHAR*)(authidentity.Domain) );
authidentity.Password = (unsigned short*)strLocalPassword.LockBuffer();
authidentity.PasswordLength = wcslen(
(WCHAR*)(authidentity.Password) );
authidentity.Flags = SEC_WINNT_AUTH_IDENTITY_UNICODE;
SOLE_AUTHENTICATION_INFO authninfo[2];
SecureZeroMemory( authninfo, sizeof(SOLE_AUTHENTICATION_INFO)*2 );
// NTLM Settings
authninfo[0].dwAuthnSvc = RPC_C_AUTHN_WINNT;
authninfo[0].dwAuthzSvc = RPC_C_AUTHZ_NONE;
authninfo[0].pAuthInfo = &authidentity;
// Kerberos Settings
authninfo[1].dwAuthnSvc = RPC_C_AUTHN_GSS_KERBEROS ;
authninfo[1].dwAuthzSvc = RPC_C_AUTHZ_NONE;
authninfo[1].pAuthInfo = &authidentity;
SOLE_AUTHENTICATION_LIST authentlist;
authentlist.cAuthInfo = 2;
authentlist.aAuthInfo = authninfo;
hres = CoInitializeSecurity(
NULL,
-1,
NULL,
