Console Session Access
What is a Console Session?
- It’s the physical desktop session (Session ID 0).
- Accessible via
mstsc /admin, it does not consume an RDS CAL. - Only one console session can exist.
Using Console Session via RDP
- Open a terminal and run:
mstsc /admin
- Enter your server IP or hostname and log in as Administrator.
- You’re now on the console session.
Best Practices
- Use
/adminfor IT/admin access only. - Reserve RDS CALs for end users only.
- Use Proxmox’s built-in console if RDP fails.
