Hello Harman,
You can use "R3trans -d" with user dv1adm. This does not work with Administrator.
Check these;
1-
Check that whether SQL Server is running?
You can do this using SQL Server Management Studio program Or you can check MSSQLSERVER services running as seen below?
2-
Can you also check the disks whether they are full?
