The information in this article applies to:
- Microsoft Windows 2000 Advanced Server
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Professional

SYMPTOMS
========
The WAIT_OBJECT_0 event is signaled even when there is no data available on the
wire to read. This causes the RasRetrieveBuffer function to fill up the
receiving buffer with a NULL character.
RESOLUTION
==========
On the client side, when the WAIT_OBJECT_0 event is signaled, if pRecvBuf
contains a NULL character, just ignore this, and then call the RasReceiveBuffer
function again.
STATUS
======
Microsoft has confirmed that this is a bug in the Microsoft products that are
listed at the beginning of this article.
MORE INFORMATION
================
Steps to Reproduce Behavior
---------------------------
dwErr = pfnRasReceiveBuffer(hPort, pRecvBuf, &dwRecvBufSize, 1, hEvent);
dwWait = WaitForSingleObject (hEvent, INFINITE);
switch (dwWait) {
case WAIT_FAILED:
OutputDebugString(_T("Wait Failed"));
return 1;
case WAIT_TIMEOUT:
dwErr = ERROR_SMM_TIMEOUT;
return 1;
case WAIT_ABANDONED:
OutputDebugString(_T("WAIT_ABANDONED\n"));
return 1;
case WAIT_OBJECT_0:
OutputDebugString(_T("The state of the object is signaled\n"));
break;
}
dwErr = pfnRasRetrieveBuffer(hPort,pRecvBuf,&dwRecvBufSize);
The server side does not send out any data. RasReceiveBuffer returns immediately.
Even though there is no data on the wire, the WAIT_OBJECT_0 event is signaled.
RasRetrieveBuffer is executed, and it fills pRecvBuf with NULL character.
