70-462 Training Kit : Cannot connect from SQL-A to SQL-Core
Currently, I have set up lab environment on my lap top (like example in 70-462 Training Kit)
After exercise 1, which is to test connectivity between machine in domain, I cannot connect from SQL-A to SQL-Core
It show error
Cannot connect to SQL-CORE
A network related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configure to allow remote connections (provider: Named pipes Provider. Error 40 – Could not open a connection to SQL Server (.net SQLClient Data provider)
Error Number: 53
In the set up phase, I can success fully join SQL-A,SQL-B,SQL-C,SQL-D and SQL-Core to DC.
Anyone has experience in this, please help.
