SQL Server

List enabled SQL Server Agent jobs

# Load required assembly
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null

# Create new object/connection
$sqlsvr = New-Object ('Microsoft.SqlServer.Management.Smo.Server') "LOCALHOST"

# Examine object
$sqlsvr.JobServer.Jobs | Where-Object {$_.IsEnabled -eq $FALSE} | Select Name,LastRunOutcome,LastRunDate

Active Directory

Look up Active Directory group members

I found this tip on ServerFault.com.

Import-Module ActiveDirectory
Get-ADGroupMember "MyADGroupName" | Select-Object name | Sort-Object name

If you wish to expand all group members from any included groups, run the command like so:

Import-Module ActiveDirectory
Get-ADGroupMember "MyADGroupName" -recursive | Select-Object name | Sort-Object name

and if you wish to instead list by Distinguished Name use this:

Import-Module ActiveDirectory
Get-ADGroupMember "MyADGroupName" -recursive | Select-Object distinguishedName | Sort-Object distinguishedName

An alternate approach is to use dsquery and dsget from the Remote Server Administration Tools (RSAT) package:

dsquery group -name "MyADGroupName" | dsget group -members -expand

With the current set of options the list of users will be by Distinguished Name.

Look up group memberships for user account

Import-Module ActiveDirectory
Get-ADPrincipalGroupMembership username | select name
name
----
Domain Users
Domain Computers
Workstation Admins
Company Users
Company Developers
AutomatedProcessingTeam

Copy all users in one group to another group

AFAIK, both groups have to be created in advance.

Import-Module ActiveDirectory
Get-ADGroupMember -Identity GROUP-A | Add-ADPrincipalGroupMembership -MemberOf GROUP-B


General

Leave out column headers in output

Here is an example of querying the Services list, limiting the results to 10 items and then sorting them, all as as stream of values:

Get-Service | Select-Object -First 10 -ExpandProperty DisplayName | sort

This gives a bare list like so:

ActiveX Installer (AxInstSV)
Adobe Acrobat Update Service
Application Experience
Application Identity
Application Information
Application Layer Gateway Service
Application Management
ASP.NET State Service
Windows Audio
Windows Audio Endpoint Builder

The -ExpandProperty parameter takes the value of an incoming object, enumerates its values and outputs each of those values as a single record on the output stream. By pointing it at a scalar property (a property that is not a collection), you get the raw value and not an object with a single property.
