NetRemoteTOD调用失败

[cnyu]

代码如下：
int nHour;
LPTIME_OF_DAY_INFO lpTodInfo = NULL;
CString strHost = "\\\\time.windows.com";
NET_API_STATUS nStatus = NetRemoteTOD(strHost.AllocSysString(), (LPBYTE*)&lpTodInfo);
if ( nStatus == NERR_Success && lpTodInfo)
{
nHour = lpTodInfo->tod_hours;
TRACE("GetTimeOK.");
}
else
{
strHost = "\\\\time.nist.gov";
nStatus = NetRemoteTOD(strHost.AllocSysString(), (LPBYTE*)&lpTodInfo);
if ( nStatus == NERR_Success && lpTodInfo)
{
TRACE("GetTimeOK.");
}
}

我用这段代码从网络服务器上获取时间，可是调用总是失败，而且会出现
First-chance exception in PowerOff.exe (KERNEL32.DLL): 0x000006BA: (no name).
的错误，请问这是什么原因？

NET_API_STATUS nStatus = NetRemoteTOD( L"\\\\time.nist.gov",(LPBYTE*)&lpTodInfo);

楼上的方法虽然编译能通过，可是仍然调用失败，并且会出现
First-chance exception in PowerOff.exe (KERNEL32.DLL): 0x000006BA: (no name).
的错误

msdn上的例子

#ifndef UNICODE
#define UNICODE
#endif

#include <stdio.h>
#include <windows.h> 
#include <lm.h>

int wmain(int argc, wchar_t *argv[])
{
   LPTIME_OF_DAY_INFO pBuf = NULL;
   NET_API_STATUS nStatus;
   LPTSTR pszServerName = NULL;

   if (argc > 2)
   {
      fwprintf(stderr, L"Usage: %s [\\\\ServerName]\n", argv[0]);
      exit(1);
   }
   // The server is not the default local computer.
   //
   if (argc == 2)
      pszServerName = argv[1];
   //
   // Call the NetRemoteTOD function.
   //
   nStatus = NetRemoteTOD(pszServerName,
                          (LPBYTE *)&pBuf);
   //
   // If the function succeeds, display the current date and time.
   //
   if (nStatus == NERR_Success)
   {
      if (pBuf != NULL)
      {
         fprintf(stderr, "\nThe current date is: %d/%d/%d\n",
                 pBuf->tod_month, pBuf->tod_day, pBuf->tod_year);
         fprintf(stderr, "The current time is: %d:%d:%d\n",
                 pBuf->tod_hours, pBuf->tod_mins, pBuf->tod_secs);
      }
   }
   //
   // Otherwise, display a system error.
   else
      fprintf(stderr, "A system error has occurred: %d\n", nStatus);
   //
   // Free the allocated buffer.
   //
   if (pBuf != NULL)
      NetApiBufferFree(pBuf);

   return 0;
}

这个例子我看了，但是我这个用法为什么会出错，而且总是调用失败？
