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.
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 Statistics since 2/6/2023 10:22:32 AM Bytes received 502580 Server Message Blocks (SMBs) received 2 Bytes transmitted 952389 Server Message Blocks (SMBs) transmitted 0 Read operations 366 Write operations 0 Raw reads denied 0 Raw writes denied 0 Network errors 0 Connections made 0 Reconnections made 0 Server disconnects 0 Sessions started 0 Hung sessions 0 Failed sessions 0 Failed operations 0 Use count 109 Failed use count 0 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

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
