Understanding the difference between mstsc /admin command and Regular RDP.
When you use mstsc /admin, you connect to the console session of the remote server.
The /admin switch allows you to connect to the server without consuming a Remote Desktop Services (RDS) Client Access License (CAL). This is helpful when there are licensing issues or no licenses are available.
Difference Between mstsc /admin and Regular RDP #
| Feature | mstsc /admin | Regular RDP |
|---|---|---|
| Session Type | Connects to the console session | Connects to a new or existing RDP session |
| Licensing | Does not require an RDS CAL | Requires an RDS CAL |
| Priority | Higher priority (console session) | Normal priority |
| Use Case | Administrative tasks, troubleshooting | Regular user access |
Done. That is all.
