Enabling PowerShell Script Execution

Running PowerShell Commands as Administrator - Needed for System/Server/User Administration

Many, if not most, administrative PowerShell commands require being run as the Administrator user or what is referred to as elevated privileges. Depending on if you are wanting to open a window from a CMD/Command prompt, or if you are opening it from a PowerShell command prompt, the process is very similar.

From PowerShell, here is the command to open an elevated PowerShell window to then run administrative command from:

PS C:\Users\jamie.DAWGLAND> Start-Process powershell -verb runas

This will open up a new PowerShell window with administrative privileges.

If you are in a CMD/DOS/Command Prompt, first type "powershell" to start PowerShell, and then just follow the above commands to open an elevated PowerShell window in which you can then run administrative commands to manage your system.

Setup Windows Command-line(CMD) Aliases Similar to Alias in Linux/UNIX

I find the ability to creating and using custom "shortcut" commands, commonly referred to "Aliases".
Traditionally, the Windows/DOS command "DOSKEY" is used to create complex command "alias" commands, to make administration of Windows/DOS based computers much easier and quicker.
As I am obviously a Linux guy, I always prefer the "Linux/UNIX" way of doing things. That's why one of the first things I do on any new Windows computer is to install the command-line "GIT" tools, which include many of the most common Linux command-line tools and configures the Windows command-line terminal to look and function like Linux terminals.
Instead of using DOSKEY, I find the solution at this URL to be best for my needs: https://superuser.com/questions/183475/how-to-alias-commands-on-windows-command-prompt

REAL Aliases with Powershell

Powershell actually has full support for "Real" aliases! It contains many built-in aliases, and has the ability to create any type of custom alias you can imagine!

To list the basic commands used to manage aliases using Powershell, use this command from a Powershell prompt:

PS C:\Users\jamie> Get-Command -Noun Alias 

The output of the command should look like this:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Cmdlet          Export-Alias                                       3.1.0.0    Microsoft.PowerShell.Utility
Cmdlet          Get-Alias                                          3.1.0.0    Microsoft.PowerShell.Utility
Cmdlet          Import-Alias                                       3.1.0.0    Microsoft.PowerShell.Utility
Cmdlet          New-Alias                                          3.1.0.0    Microsoft.PowerShell.Utility
Cmdlet          Set-Alias                                          3.1.0.0    Microsoft.PowerShell.Utility


PS C:\Users\jamie>

Use the Get-Alias commandlet to list the aliases available in the current environment:

PS C:\Users\jamie> Get-Alias -Definition Get-ChildItem

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           dir -> Get-ChildItem
Alias           gci -> Get-ChildItem
Alias           ls -> Get-ChildItem

PS C:\Users\jamie>

To see the definition of a single alias, use the "Name" parameter:

PS C:\Users\jamie> Get-Alias -Name gci

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           gci -> Get-ChildItem

PS C:\Users\jamie>

Use the Set-Alias command to create a new custom alias:

PS C:\Users\jamie> Set-Alias -Name chkadm -Value "(New-Object Security.Principal.WindowsPrincipal([Security.Principal.WindowsIdentity]::GetCurrent())).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)"

Here is a URl at Microsoft listing all Powershell built-in aliases, as well as information on how to create your own custom alias for use with Powershell.

DOS/CMD - Miscellaneous Command Line Commands

This command shows how long a Windows computer has been powered on since the last time it was shut down or rebooted, which can be helpful when diagnosing issues with a sluggish, slow-responding system. this is also known as a system's "Uptime". This is the command along with its output. Note the line starting with "Statistics since", which shows the actual date and time the system was last powered on.

C:\Users\Administrator.DAWGLAND>net stats workstation
Workstation Statistics for \\WIN22VM01

The command completed successfully.

You can trim/filter out most of the output, so that you only get the actual info you are looking for, in this case, the two-word phrase "Statistics since". This is how you would do it, "piping" the output of the previous command into the "findstr" command to find the line(s) containg the phrase "Statics since", case sensitive:

PS C:\Users\Administrator.DAWGLAND> net stats workstation | findstr /C:"Statistics since"
Statistics since 2/6/2023 10:22:32 AM

You can shorten the command even further if you instead of searching for the two-word phrase "Statistics since", you can just search for/find the one word "since", as it's the only line in the entire output of the "net stats workstation" command that contains that one word. Here's an example:

PS C:\Users\Administrator.DAWGLAND> net stats workstation | findstr since
Statistics since 2/6/2023 10:22:32 AM

Enabling & Configuring OpenSSH Server on Windows Using PowerShell

First, confirm the current state of the OpenSSH Server and OpenSSH Clients, whether either are installed, enabled, and configured.

Type this command to check the current status of both the server and client:

PS C:\Users\Administrator.DAWGLAND> Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'


Name  : OpenSSH.Client~~~~0.0.1.0
State : Installed

Name  : OpenSSH.Server~~~~0.0.1.0
State : NotPresent

As you can see from output of the above command, OpenSSH Client is installed on the server, but OpenSSH Server is "NotPresent", meaning it's not been installed/enabled on the server yet. Will fix that next so that users can log into the Windows server using SSH, the Secure Shell to remotely connect annd manage the server.

Use this PowerShell command to install/enable the OpenSSH Server:

PS C:\Users\Administrator.DAWGLAND> Add-WindowsCapability -Online -Name OpenSSH.Server~~~~0.0.1.0


Path          :
Online        : True
RestartNeeded : False

Run the previous "Get-WindowsCapability -Online | ? Name -like 'OpenSSH*'" command and confirm that OpenSSH Server is now installed.

Next, manually start the OpenSSH service, like this:

PS C:\Users\Administrator.DAWGLAND> Start-Service sshd
WARNING: Waiting for service 'OpenSSH SSH Server (sshd)' to start...

You can use this command to confirm the SSH server service has been started and is now running:

PS C:\Users\Administrator.DAWGLAND> Get-Service | findstr -i sshd
Running  sshd               OpenSSH SSH Server

Use this command to check on the startup type, referring to the setting to have the OpenSSH Server startup automatically on each computer reboot or power on.

PS C:\Users\jamie.DAWGLAND> Get-Service -Name sshd | Select -property name,starttype

Name StartType
---- ---------
sshd    Manual

As you can see from the output of the above command, the "StartType" for "sshd"(sshd stands for "SecureSHell Daemon". Daemon is another word for "Server".

As we want to always be able to securly log into the server remotely to perform routine maintenance and configuration, we want to configure the SSHD(OpenSSH Server) to automatically start up every time the computer is started up or rebooted. Here's how:

PS C:\Users\jamie\Downloads> Set-Service -Name sshd -StartupType 'Automatic'

Now, confirm it's set to start up automatically:

PS C:\Users\jamie\Downloads> Get-Service -Name sshd | Select -property name,star
ttype

Name StartType
---- ---------
sshd Automatic

Confirm firewall rule has been created for the SSH service:

PS C:\Users\jamie.DAWGLAND> Get-NetFirewallRule -Name *ssh*


Name                          : OpenSSH-Server-In-TCP
DisplayName                   : OpenSSH SSH Server (sshd)
Description                   : Inbound rule for OpenSSH SSH Server (sshd)      
DisplayGroup                  : OpenSSH Server
Group                         : OpenSSH Server
Enabled                       : True
Profile                       : Any
Platform                      : {}
Direction                     : Inbound
Action                        : Allow
EdgeTraversalPolicy           : Block
LooseSourceMapping            : False
LocalOnlyMapping              : False
Owner                         :
PrimaryStatus                 : OK
Status                        : The rule was parsed successfully from the       
                                store. (65536)
EnforcementStatus             : NotApplicable
PolicyStoreSource             : PersistentStore
PolicyStoreSourceType         : Local
RemoteDynamicKeywordAddresses : {}

Finally, last, but not least, configure PowerShell to be the default environment when logging into the Windows server using SSH protocol. Here's the command:

PS C:\Users\jamie.DAWGLAND> New-ItemProperty -Path "HKLM:\SOFTWARE\OpenSSH" -Name DefaultShell -Value "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -PropertyType String -Force


DefaultShell : C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe        
PSPath       : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\ 
               OpenSSH
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE  
PSChildName  : OpenSSH
PSDrive      : HKLM
PSProvider   : Microsoft.PowerShell.Core\Registry

AD-DS - Active Directory - Domain Services

Here is the DOS/CMD command to show the current state of each of the 5 FSMO roles configured for MS AD-DS using the "netdom query fsmo" command:

C:\Users\Administrator.DAWGLAND>netdom query fsmo
Schema master               win19vm10.dawgland.com
Domain naming master        win19vm10.dawgland.com
PDC                         win19vm10.dawgland.com
RID pool manager            win19vm10.dawgland.com
Infrastructure master       win19vm10.dawgland.com
The command completed successfully.

As you can see from the output of the "netdom query fsmo" command, all 5 roles are hosted on the same Windows Server 2019 machine/VM. This is required information when it comes time to migrate AD-DS from an older server to a newwer server with a newer version of MS Windows Server.

Rename Computer Using PowerShell - MUST BE DONE FROM ADMINISTRATOR ELEVATED SHELL, OR THE COMMAND WILL FAIL!!!
First, open up an elevated shell sos you are the "Administrator", as follows:

PS C:\Users\Jamie Rubinstein> Start-Process powershell -verb runas

It will prompt you to allow it to make changes - Click on "YES"!
It will then open up a new PowerShell window, most likely with a blue background to remind you to be careful with anything you type since you are not in
Adminstrator mode, which can be very dangerous if you are not sure about what commands to type!

In the new Adminstrator shell window, type the following command to rename your computer to what you want it to be:

PS C:\WindowPS C:\Users\Jamie Rubinstein> Rename-Computer -NewName "win11tinyvm02"

It will display this notice:

WARNING: The changes will take effect after you restart the computer DESKTOP-6462IKR.
PS C:\Windows\system32>

You can reboot the system immediately from the PowerShell command window, by typing this command:

PS C:\Users\Jamie Rubinstein> shutdown /r /t 0

If you'd rather just shut the system down for now, instead of rebooting, change the /r in the above command to /s, like this:

PS C:\Users\Jamie Rubinstein> shutdown /s /t 0

Changing lock sceen time-out using the command line:
Open a new command-prompt window as Administrator, and use this command, substituting the last number "300" to what you want, without the quotes. "300" equals 5 minutes. "0" equals "NEVER".
