View SQL Server information using Transact-SQL script

Recently one of our clients requested information about their SQL Server infrastructure which we manage. In order to complete this task, I’ve written the following Transact-SQL script to retrieve information about SQL Server infrastructure.

This script is compatible with SQL Server 2005 and above:
