Can someone explain when and how often each of the Windows RPC ports are used? The "core" ones I understand are:
- Port 135
- Port 137
- Port 139
- Higher ports that are published by Port 135's "catalog"
Then I heard that Port 145 came into the mix to "make things better" with NBT/TCP but I'm not sure how this fits in with the sequence of a Windows client initiating an RPC action.
Can anyone help me fix my understanding of RPC ports once and for all?
