As per https   msdn microsoft com en-us library ms180065 aspx   DBCC USEROPTIONS reports an isolation level of  read committed snapshot  when the database option READ COMMITTED SNAPSHOT is set to ON and the transaction isolation level is set to  read committed   The actual isolation level is read committed   Also in SQL Server Management Studio  in database properties under Options- Miscellaneous there is  Is Read Committed Snapshot On  option status
