Not that it is going to affect the bug that much but just setting the 
ui variable to NULL is a memory leak.  According to the MSDN docs:

bufptr 
  Pointer to the buffer in which the data set with the level parameter 
  is stored. The returned buffer should be deallocated using the 
  NetApiBufferFree function. 

Even though it would be unusual that a failed call would allocate
anything in ui, it is possible that the malloc happens before the 
actual call.  I would change 

	ui = NULL;

to 

	NetApiBufferFree( (LPVOID *)&ui);

(if my C coding is not too stale).
