This problem occurs because the cross-database chaining option has been disabled for the RTC database and for the RTCDyn database. The cross-database chaining option must always be enabled. The option is disabled when you detach and re-attach the databases.
To resolve this problem, follow these steps to allow cross-database ownership chaining for the RTC database and for the RTCdyn database:
- On a computer that is running Microsoft SQL Server, connect to the RTC database, and then run the following SQL command from SQL Server Management Studio:
sp_dboption rtc, 'db chaining', TRUE
- Connect to the RTCdyn database, and then run the following SQL command from SQL Server Management Studio:
sp_dboption rtcdyn, 'db chaining', TRUE
- Start the Front End services.
