# Reconnaissance

 This section can be used before and after the initial attack vectors

### Using simple CMD

#### Domain name

```
ipconfig /all
```

#### Domain Controllers

```
nslookup <domain>
```

```
nltest /dclist:{domainname}
```

```
echo %logonserver%
```

## On Linux

#### Domain name

```
cat /etc/resolv.conf
```

Or scan machines with CrackMapExec:

```
cme smb 192.168.12.0/24
```

#### Domain controller

As domain controllers are often DNS Servers, you can simply use these commands:

```bash
systemd-resolve --status | grep "DNS Servers"
```

or :

```bash
nmcli dev show | grep DNS
```
