Your password may have expired or the remote PC might not accept blank passwords. Try connecting again. If this keeps happening, ask your admin or tech support for help.

Error code: 0x519

Can anyone give me some advice on how to fix this Remote Desktop 0×519 error?”

Four methods to fix Remote Desktop 0×519 error

When remote into another computer using Remote Desktop, we sometimes encounter problems. To fix the Remote Desktop 0×519 error, here we list four methods for you.

Method 1. Check out the password

According to the error message, the first thing you need to do is to check out if your password is expired. If you’re not sure about this, the easiest way is to change your computer password and then try to access the computer with a new password and new credential.

Method 2. Restart the RDP service

The second method is to restart the RDP service, cause sometimes restart fixes everything.

 Step 1. Press Win + R to open the Run dialog box. Type in “services.msc” and press OK.

Services.msc

Step 2. Locate and right-click on the Remote Desktop Services, then choose Restart to restart your service.

Restart Remote Desktop Services

Method 3. Disable the Network Level Authentication

Network Level Authentication was designed to only allow users who have authenticated themselves to the network to connect to your computer. Therefore, sometimes, it will block the initiation of a remote desktop connection from those who are not authenticated. You can disable the NLA to see if this can solve the Remote Desktop 0×519 error.

 Step 1. Press Win + R to invoke the Run dialog box. Then type in “sysdm.cpl” and hit OK to open System Properties.

Run Command Sysdm.cpl

Step 2. Go to the Remote tab and uncheck Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended).

Uncheck Identity Verification

Method 4. Change Firewall settings

Sometimes, Windows Firewall may block the remote connection as well, so you can try to change the Firewall settings.

 Step 1. Press Win + R and then type in “control panel” and hit OK to open Control Panel.

Run Box Control Panel

Step 2. Navigate here: Control Panel > System and Security > Windows Defender Firewall.

Defender Firewall

Step 3. Click Advanced settings in the left sidebar.

Step 4. Click Inbound Rules, find Remote Desktop - User Mode (TCP-In), and check whether the rule is enabled. If not, right-click it and then choose Enable Rule.
