Metasploitable 3 is notoriously unstable under heavy SMB exploits. Solution: Don't use EternalBlue. Use exploit/windows/smb/ms17_010_psexec instead, which is less aggressive, or stick to WinRM. "I can't access port 445 from Kali." Windows Firewall might be blocking it. Revert the VM snapshot. Metasploitable 3 resets firewall rules on boot, but sometimes virtualization interfaces change. Ensure both VMs are on the exact same Host-Only adapter. "The Jenkins console is locked." The default credentials changed. Check the build.log from when you created the VM. Alternatively, try admin:admin , vagrant:vagrant , or blank. "My reverse shell isn't connecting." Windows Firewall is blocking inbound connections, but outbound is usually open. Ensure your Kali listener ( nc -lvnp 4444 ) is running. Use LHOST=192.168.56.101 and ensure no host firewall on Kali is blocking. Conclusion: What Did We Learn? This walkthrough of Metasploitable 3 Windows demonstrates a critical truth: Complex exploits (EternalBlue) are cool, but simple misconfigurations (WinRM with weak passwords) are how real breaches happen.

nmap -sV -sC -O -p 80,445,3389,4848,8172,9200 192.168.56.102 The presence of WinRM (port 47001) and SMB signing disabled will be our eventual keys to the kingdom. Step 2.3: Enum4linux (The SMB Goldmine) Windows Loves SMB. Misconfigured shares are the low-hanging fruit.
