A user session on the server could not be created. Try to start the client again. If the problem continues, contact the Microsoft Dynamics AX Administrator.
This usually caused by Hard-disk failure due to Not Accessible, Out of Memory Spaces or even corrupted drives.
Microsoft Dynamics AX cannot create a session record in the Databases and you will not be able to open or access Microsoft Dynamics AX Client.
- Check your SQL Server where your Microsoft Dynamics AX Databases was stored.
- Check if local drives where AX Databases stored are accessible and still enough memory spaces. If full try to clean some temporary log files or try to increase your local drive spaces.
Show’s Data(D:) is already full and no enough spaces to create any records.
Try again to open Microsoft Dynamics AX Client.
