Linked server queries that use MSDASQL fail with error 7416

Linked server queries that use the MSDASQL (OLE DB Provider for ODBC Drivers) provider and specify a provider string (@ provstr ) fail and return the following error message:

Msg 7416, Level 16

Access to the remote server is denied because no login-mapping exists.

A stricter connection validation check in the Database Engine can reject connections for certain linked server configurations that use the MSDASQL provider, even if earlier builds allowed those connections.

For more information and workarounds, see Linked server queries that use MSDASQL fail with error 7416.

Access violation when you query sys.dm_exec_requests during database recovery

Queries against sys.dm_exec_requests might raise an access violation and generate a dump file if they run while a database is still recovering. This issue can occur during a database RESTORE operation, during startup recovery, or before an availability group replica finishes coming online.

The SQL Server error log contains entries that resemble the following text:

The database '<DatabaseName>' is marked RESTORING and is in a state that does not allow recovery to be run.

***Stack Dump being sent to <SQLServerLogFolder>\SQLDump0215.txt

SqlDumpExceptionHandler: Process 77 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process. ...
