SYMPTOMS
When the program you are using loads or unloads the Iphlpapi.dll file on your computer running Windows NT 4.0 (for example, by a Winsock 2.0 layered service provider), a system resource leak may occur, especially a memory or a handle leak.



CAUSE
This behavior occurs because part of the source code for the Iphlpapi.dll file causes a leak in the file handle created in OpenIpDriver and in three critical sections allocated in the DLL Entry function.
