Kim tra SQL Server bng Windows PowerShell – Phn 4 Phn 1 ca lot bài này ã gii thiu v kim tra u tiên trên SQL Server – các ping mt host. Phn 2 là gii thiu v cách kim tra tt c các dch v ca Windows có liên quan n SQL Server và phn ba là cách kim tra các thông tin phn cng và phn mm.
