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. Trong phn tip theo
này, chúng tôi s gii thiu cho các bn các thu thp các thông tin v card mng và  a cng
t máy ch.
