From a hackers point of view when thinking about writing code to enumerate information and call remote procedures; Exactly what can be called is hard to know, except for the things that are already known.

There is little documentation available outside of Microsoft that describes the different calls available after a null session has been established. The only thing hackers can do is try whatever they can think of and see what happens, then try to understand why it works the way it does. There could be things nobody outside Microsoft knows of yet.

A lot of what is known though is wrote into tools to enumerate this information, tools such as penetration scanners, DumpACL, epdump, Getmac and even net view use these techniques. These tools are unfortunately a doubled edged sword, a balance between usability and security.

What this does tell us though is that these NULL sessions, RPC etc should not be allowed on public networks or evenprivate networks on some occasions if security is of concern. Examples of these functions being called can be seen in user2sid.

Follow the comments to see exactly where the APIs are used to enumerate the relevant information;. One way to this is by using the Net Use command with an empty password. The most common command to use when enumerating Windows ahares is nbtstat. Nbtstat is a Windows command that can displays information about a target.

This command will display necessary information about target. Let's look at the following output after executing this command on our target. Here we can already see some pretty interesting information, such as the MAC.

Let's break this table up a bit. The first line in the table tells us information about the computer. Unique means that this computer name must only have one IP address assigned to it.
