SYMPTOMS
When an application repeatedly calls the RasEnumEntries API, system performance slows down and disk activity increases.



CAUSE
The Win32 API RasEnumEntries does not deallocate all of the memory it needs to process the phonebook. Any process repeatedly calling this API continues to grow. The amount of memory lost is related to the size of the phonebook and the frequency in which RasEnumEntries is called. When the application terminates, all memory is released to the system.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post additional information here in the Microsoft Knowledge Base as it becomes available.

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
