Unable to log on to Microsoft Dynamics AX

Error: Unable to log on to Microsoft Dynamics AX.

It can happen that even though AOS and SQL Server seem to be running fine and with no errors in the EventLogs, you get an "Unable to log on to Microsoft Dynamics AX" error message when opening the AX client. This is a problem with stored passwords in the client machine.

Solution

Please navigate to "Control Panel-->User Accounts-->Manage Password" ,select the particular user and change to 'Advanced' tab and click 'Manage Passwords' and change the existing password (or) Remove the Password.
