InitiateShutdown error with RPC_S_SERVER_UNAVAILABLE error for the remote computer

Question

I am trying to reboot a remote computer using the InitiateShutdown API using the following code, but with an error RPC_S_SERVER_UNAVAILABLEor error 1722code:

//Process is running as administrator

//Select a remote machine to reboot:
//INFO: Tried it with and w/o two opening slashes.
LPCTSTR pServerName = L"192.168.42.105";
//Or use 127.0.0.1 if you don't have access to another machine on your network.
//This will attempt to reboot your local machine.
//In that case make sure to call shutdown /a /m \\127.0.0.1 to cancel it.

if(AdjustPrivilege(NULL, L"SeShutdownPrivilege", TRUE) &&
    AdjustPrivilege(pServerName, L"SeRemoteShutdownPrivilege", TRUE))
{
    int nErrorCode = ::InitiateShutdown(pServerName, NULL, 30,
                                        SHUTDOWN_INSTALL_UPDATES | SHUTDOWN_RESTART, 0);

    //Receive nErrorCode == 1722, or RPC_S_SERVER_UNAVAILABLE
}



BOOL AdjustPrivilege(LPCTSTR pStrMachine, LPCTSTR pPrivilegeName, BOOL bEnable)
{
    HANDLE hToken; 
    TOKEN_PRIVILEGES tkp;
    BOOL bRes = FALSE;

    if(!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
        return FALSE; 

    if(LookupPrivilegeValue(pStrMachine, pPrivilegeName, &tkp.Privileges[0].Luid))
    {
        tkp.PrivilegeCount = 1;  
        tkp.Privileges[0].Attributes = bEnable ? SE_PRIVILEGE_ENABLED : SE_PRIVILEGE_REMOVED; 

        bRes = AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
        int nOSError = GetLastError();
        if(bRes)
        {
            if(nOSError != ERROR_SUCCESS)
                bRes = FALSE;
        }
    }

    CloseHandle(hToken);

    return bRes;
}

So, in order to prepare for the execution of this code, I do the following on a computer thisthat is equal Windows 7 Pro(as I would do for Microsoft shutdown ):

• Run the "administrator" to allow SMB access to the registered user D1on the computer 192.168.42.105(for this answer ):

 NET USE \\192.168.42.105\IPC$ 1234 /USER:D1

• Run the process with my code above "as administrator".

192.168.42.105, Windows 7 Pro ( )

• , , "Private" " "

• :

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

  LocalAccountTokenFilterPolicy = DWORD: 1

• RUN secpol.msc, " ", " ", " ", " ". "Everyone" "Force shutdown from remote system". ( !)

, shutdown , :

shutdown /r /m \\192.168.42.105 /t 30
