DYNAMICS NAV ERROR "The Service Principal Name (Delegation) configuration has been set incorrectly. "

Hello reader, today i received the above error when i attempted to login to Dynamics NAV server from my client PC.
Before i encountered the error everything worked correctly a few days back. I realized i had updated my password from the domain user account which i use to access NAV on the server.

My PC was set to use WINDOWS authentication.
I realised that my username and password i used to login to my PC is different from the domain account login information for accessing Dynamics NAV server.
I suspected the difference could have been the problem after checking up a few blogs online.

If you have encountered a similar error try this to fix.

• Change your Clients credential type to UserName on your client PC.
• Once you run NAV, it will prompt you for username and password
• Login using the domain account information you use to access the NAV server instance on your Server.

if you don't know how to change the client credential type follow these steps;

1. Open file explorer and navigate to C:\Users\[Current User]\AppData\Roaming\Microsoft\Microsoft Dynamics NAV\[folder 110 for NAV 2018, 90 for NAV 2017, 71 for NAV 2013]
2. open clientsettings.config file
3. Update clientCredentialType="UserName"
4. Save and exit
5. Run NAV again and it will prompt you for username & password

Please note that the square brackets above are a place holder

here is mine C:\Users\Mark\AppData\Roaming\Microsoft\Microsoft Dynamics NAV\110

You should be able to login successfully.
Good luck
