Here are step-by-step instructions to troubleshoot and potentially fix the "Remote desktop cannot connect to the remote computer" issue:

1. Enable Remote Access on the Remote Computer:

On the remote computer:

Open Control Panel.

Go to System and Security > System.

Click Remote settings on the left-hand side.

Under the Remote tab, check the box for "Allow remote connections to this computer".

Click Select Users to specify who can connect remotely.

Click OK to save the changes.

2. Verify Remote Computer Status:

Check if the remote computer is turned on and connected to the network.

If it's in sleep mode, wake it up.

Ensure it's not in a remote shutdown state.

3. Check Network Connectivity and Firewall:

Verify both computers are on the same network or have a stable internet connection.

On the remote computer:

Open Control Panel and go to System and Security > Windows Defender Firewall.

Click Allow an app or feature through Windows Defender Firewall.

Locate Remote Desktop and check both Private and Public boxes.

Click OK.

4. Confirm Computer Name or IP Address:

Double-check the hostname or IP address you're using to connect.

Find this information on the remote computer:

Open Control Panel > System and Security > System.

Look under Computer name, domain, and workgroup settings.

5. Address Additional Potential Issues:

Ensure compatible Windows versions on both computers.

Check for pending Windows updates and install them.

Temporarily disable antivirus or firewall software on both computers (if applicable).

6. Seek Further Assistance:

If the issue persists, consult event logs on both computers for clues.

Contact the administrator of the remote computer for more advanced troubleshooting.
