I know the case was wrong..
Well here is the sprintf and code.. it blows up on the sprintf, and
the data in the command looks funny when I inspect it so I figured
that the alignment was off..

i tried this:
sprintf( gooddata, "%8lu %.70S\n", pJob->JobId, pJob->Command );
but it blew up.

then this to verify something worked (and it did but it does not get
me the job command text:
sprintf( gooddata, "%8lu \n", pJob->JobId );

finally this:

int nSize = wcstombs(szTarget,pJob->Command,2048);
This blew up also.

Here is the original code with some stuff I tried in comments etc.:

wchar_t  Servername[256];
AT_ENUM *PointerToBuffer = NULL;
AT_ENUM *pJob = NULL;
DWORD PreferredMaximuLength = 8192;
DWORD EntriesRead = 0;
DWORD TotalEntries = 0;
DWORD dwResumeHandle = 0;
bool bGoForIt = true;
NET_API_STATUS theStatus;
DWORD index = 0;
int nMessages = 0;
//	mbstowcs( Servername, "vectrajtk", 256 );
		Servername[0] = L'\0';
	while (bGoForIt)
   {
		theStatus = NetScheduleJobEnum(
	 Servername,	//Pointer to a Unicode string containing the
name of the remote server on which the function is to execute. A NULL
pointer or string specifies the local computer.
    (BYTE **) &PointerToBuffer, //On return a pointer to the return
information structure is returned in the address pointed to by
PointerToBuffer. The return information structure is an array of
AT_ENUM data structures.
    PreferredMaximuLength, //Preferred maximum length, in 8-bit bytes
of returned data.
    &EntriesRead, //Pointer to a DWORD that contains the actual
enumerated element count.
    &TotalEntries, //Pointer to a DWORD that contains the total number
of entries that could have been enumerated from the current resume
position.
    &dwResumeHandle //Pointer to a DWORD that contains ResumeHandle,
which is used to continue an job enumeration. The handle should be
zero on the first call and left unchanged for subsequent calls. If
ResumeHandle is NULL, then no resume handle is stored.
   );

		if ( theStatus != ERROR_SUCCESS && theStatus !=
ERROR_MORE_DATA )
		{
		char darnit[1024];
      	sprintf(darnit, "Doh! theStatus = %lu\n", theStatus );
   		MessageBox(darnit,"cant continue",MB_OK);
      	return;
		}

		for ( pJob = PointerToBuffer, index = 0; index <
EntriesRead; ++ index, ++ pJob )
		{
      char gooddata[2024];
//			sprintf( gooddata, "%8lu \n", pJob->JobId );
//			sprintf( gooddata, "%8lu %.70S\n",
pJob->JobId, pJob->Command );
		char szTarget[2048];
      	memset(szTarget,0,2048);
		int nSize = wcstombs(szTarget,pJob->Command,2048);
			sprintf( gooddata, "%8lu %s\n", pJob->JobId,
szTarget );
         MessageBox(gooddata,"GOOD DATA.. keep on going",MB_OK);
         nMessages++;
		}

		if ( PointerToBuffer != NULL )
			NetApiBufferFree( PointerToBuffer );

		if ( theStatus == ERROR_SUCCESS )
			bGoForIt = false;
	}
   if (nMessages < 1)
   {
   	MessageBox("no data found","at an end here",MB_OK);
      return;
   }
