Cause: Got above error when I tried to access my SharePoint site and Central administration. The error says that current user is not able to access the database. Everything was working fine until I've crashed my VMWare and restarted.

Resolution:
1. Open Services.msc
2. Restarted SQL Server (SHAREPOINT) service
3. Noticed that the following services was disabled. Enabled both the service.
SQL Server Agent (SHAREPOINT)
SQL Server Browser
