Also, what is the full script you were running when you called
Win32::IPHelper::GetNetworkParams? I have a suspicion you had a C stack
overflow based on and looking at the asm of Iphlpapi.DLL with that file
version.
Fault Module Name: Iphlpapi.DLL
Fault Module Version: 6.1.7601.17514
Fault Module Timestamp: 4ce7c6da
Exception Code: c0000005
