SYMPTOMS
A handle leak may occur while using the RasDial API. After the connection is closed using RasHangUp, you may notice that the handle count of the application does not return to the value before the RasDial call. This is more noticeable on applications that continually make connections using RasDial and then close them using RasHangup.



CAUSE
RasDial opens a handle to the process token and does not close it, which causes the handle count to increase every time RasDial is called.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
