A DateRange Table Valued function

The function is an inline table-valued function (or sometimes called a parameterised view) so it can be used just like a view or a table but needs parameters. It generates a single-column table of datetime2 with rows differing by any multiple of any of the dateparts that SQL Server provides.

A simple powershell script to look up server hardware and OS information

This is a simple powershell script to query and display hardware and OS information from a remote computer.

It uses CIM (Common Information Model) that is available since Powershell version 3 so as long as you have version 3 and up, you should be able to run this script against any server that you have access to.

Look up AD user properties using powershell

I realize that this is a bit of a lengthy script for something that you can use a one liner in the power shell:

Example:

Get-ADUser

But I needed to highlight certain properties of given user and take certain actions based on the values. And the result is this power shell script.
