Hello, I have the same problem:
I am using WinPCap 2.3 beta, in some machines with W2k the function Get Adapter Names returned a list empty. A friend removed the NETBEUI protocol, then the function returned a list with adapter names and the aplication works Ok. but in another machines with W2k, removing NETBEUI return a list empty. Then, I increased the size of the buffer passed to PacketGetAdapterNames(), Uninstall and Reinstall winpcap, but nothing. After that, I write a procedure to get the adapter Name from register, and completed it with prefix "\Device\Packet_", and the function PacketOpenAdapter returned Null.
