RasEnumEntries() API Leaks Memory

• Microsoft Windows NT Workstation versions 3.51, 4.0
• Microsoft Windows NT Server versions 3.51, 4.0

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.
