How do I find out what process opened what port?

I want a method of finding out what process opened what port without the aid of an external application. I.e. no netstat or other tools like it.

You need to use the IP helper functions. More specifically GetExtendedTcpTable and GetExtendedUdpTable.

For example, for GetExtendedUdpTable, you can pass in MIB_UDPTABLE_OWNER_PID as the TableClass and you will be able to receive the PID of the process that issued the call to bind for the UDP endpoint.
