Solving "No Suitable Default Server Credential Exists on This System" Error

When systems don’t have suitable server credentials for authentication, you can be faced with errors points when attempting server connection requests. The error message reads “No suitable default server credential exists on this system” and provides no other clues as to the cause. This leaves many system and network administrators with the dilemma of having to troubleshoot and fix the system.

Fortunately, there is a solution. This guide will take you step-by-step through the process of troubleshooting and restoring authentication to allow for successful server connection requests.

Step 1: check the permissions

The first step requires you to determine if the machine you are trying to connect has permission to access the remote computer. This can be done by accessing the user accounts of the local computer, right-clicking on the account of the local machine, then selecting 'properties'. This will display a list of the user's account information. Scroll down to the bottom and click the “Advanced” tab. Here you can view the “Combined Security Groups” which grants and controls user access. See if the user has access to the server and if not, grant it.

Step 2: Create a new server credential

If there is no server credential present, you'll need to create one. To do this, select “Create New Server Credential” from the drop-down list. You will be prompted to provide a username and password. Insert the credentials and click “OK.”

Step 3: Re-establish the connection

The next step is to reconnect to the server and verify the credentials. From the command prompt run the “nltest” command (this will test the network logon) and enter the credentials when prompted. If the credentials are verified and accepted, the connection is now established.

Step 4: Test the connection

The final step is to test the connection. To do this, run a ping command between the two systems and check the response. If it responds with a “Success” message, then the connection is established, and the “No suitable default server credential exists on this system” error has been resolved.
