PowerShell: Get a List of AD Groups a specific user is a member of

by Samuel Mitchell, posted in Microsoft, windows, Windows server

Powershell is very versatile and with this wonderful tool, I will share how to get the subject result.

There are two ways of doing this:

  1. Using the cmdlet

Get-ADPrincipalGroupMembership [username] | Format-Table Name -AutoSize

I used the cmdlet with Format-table to output property Name in a table format

2. Using the cmdlet

Get-ADUser [username] -Properties memberof | Select -ExpandProperty memberof | Get-ADGroup | Format-Table Name -AutoSize

I used the additional parameter -Properties to get the variable MemberOf then use the Select cmdlet to expand the array then pipe it to the Get-ADGroup to get the name of group to list it in a table format.

Microsoft: Manipulating Windows Network Adapter using PowerShell

by Samuel Mitchell, posted in Microsoft, Routing & Switching, windows, Windows server, Wireless

This article is about configuring the network adapter using PowerShell cmdlet:

To get a list of the names of physical network adapter, the following command was used:

Get-NetAdapter -Physical

To get the IP address assigned to the network adapter:

Get-NetIPAddress | Format-Table

To enable/disable the network adapter:

Enable-NetAdapter [-Name] “NetAdapterName”

Disable-NetAdapter [-Name] “NetAdapterName”

Restart-NetAdapter [-Name] “NetAdapterName”

To set dynamic IP address assignment for network adapter:

Set-NetIPAddress -AddressFamily IPv4 -PrefixOrigin Dhcp

To set static IP address for network adapter:

New-NetIPAddress -InterfaceIndex [NetAdapterIndex] -IPAddress 192.168.0.1 -PrefixLength 24 -DefaultGateway 192.168.0.5

Set-NetIPAddress -InterfaceIndex [index] -IPAddress 10.0.0.9 -PrefixLength 24

To set DNS IP address for network adapter:

Set-DnsClientServerAddress -InterfaceIndex 12 -ServerAddresses(“10.0.0.1”,“10.0.0.2”)

Or

Set-DnsClientServerAddress -InterfaceIndex 12 -ResetServerAddresses

Manipulating Windows Network Adapter using Network Shell

by Samuel Mitchell, posted in Microsoft, Routing & Switching, windows, Windows server, Wireless

This adventure of configuring the network adapter started when I required admin rights to modify the settings because UAC (User Access Control) was disabled which prevented the prompting of admin privilege. The challenge was that I did not want to log off or switch user account hence I had to resort to using elevated privilege for the command prompt and utilize the network shell.

To get a list of the names of network adapter, the following command was used:

netsh interface show interface

To get the IP address assigned to the network adapter:

netsh interface ipv4 show addresses

To enable/disable the network adapter:

netsh interface set interface name=”NameOfInterface” admin=[ENABLED/DISABLED]

To set dynamic IP address assignment for network adapter:

netsh interface ipv4 set address source=dhcp

To set static IP address for network adapter:

netsh interface ipv4 set address static 10.0.0.9 255.255.255.0 10.0.0.1

To set DNS IP address for network adapter:

netsh interface ipv4 set dnsservers source=dhcp

Or

netsh interface ipv4 set dnsservers static 10.0.0.10 primary

For WLAN network adapter:

netsh wlan show interfaces

Show the Wireless networks broadcasting:

netsh wlan show networks

Show the WLAN profiles on computer:

netsh wlan show profiles

Connect to one of the WLAN profile configured on computer:

netsh wlan connect name=[ProfileName]

Disconnect from the currently connected WLAN SSID

network wlan disconnect name=[InterfaceName]

Installing Windows Features using PowerShell

by Samuel Mitchell, posted in Microsoft, Windows server

I was on a drive to enable SNMP feature on all our Windows 2012 R2 servers in order to monitor the CPU, Memory and Disk utilization through WMI.

Trying to do this manually using the Windows Roles and Features for over 40 servers was not practical as it was time consuming. As a result, I venture out to seek a way to do this on a widescale in the shortest possible time.

Now here comes Powershell, it has save the day with it’s easy-to-use cmdlets and remote execution from any Windows machine.

I am now going take this opportunity to show what I have done to complete this task.

The following cmdlet is what you will use to install any windows features from the server roles:

This cmdlet is used to get the Windows features that are currently installed on the server:

Get-WindowsFeature [FeatureName] -computerName [NameOfComputer]

You can include the Features name in the command in order to get the status of the particular feature.

This cmdlet is used to install the windows features:

Install-WindowsFeature [FeatureName] -computerName [NameOfComputer]

Using the cmdlets above, the following commands were executed to install the SNMP-Service feature:

PS C:\> Get-WindowsFeature SNMP-Service -ComputerName TestWinServer

results:

SNMP-GetFeature

Installing Windows features SNMP-Service for the 2012 R2 server TestWinServer

PS C:\> Install-WindowsFeature SNMP-Service -ComputerName TestWinServer

Results:

SNMP-InstallFeature

After installing this feature, I was able to configure the SNMP services and set my monitoring tool to pull the information from WMI using snmp.

I hope this article was helpful.
