Hi there,
Can you try opening command prompt, or just search CMD and then enter.
If you type in: whoami and then enter you will see what the local account name is.
Add that local account name in the Remote desktop app from which you try to remote connect from.
Open the Remote Desktop Connection app:
Press Windows + R on your keyboard to open the Run dialog box.
Type mstsc and press Enter. This will open the Remote Desktop Connection window.
Enter the computer name or IP address:
In the Computer field, type the IP address or the name of the remote computer you want to connect to.
Expand the options:
Click on the Show Options button at the bottom-left corner of the window. This will expand the window and show more settings.
Enter the Username you have previously found with the whoami command:
Under the General tab, in the User name field, type the username.
If you want the RDP client to remember your credentials, check the box that says Allow me to save credentials.
This will let you avoid entering the username and password every time you connect.
Connect:
Click Connect. You will be prompted to enter your password for the account specified.
Once entered, you can check Remember me if you want RDP to save your password.
Save the RDP profile (Optional):
If you frequently use this connection, you can save the settings as an RDP file.
Under the General tab, click Save As... and choose a location to save the RDP file.
Next time, simply double-click the saved file to launch the RDP session with the pre-filled computer name and username.
