powershell – Find all computers in a domain or OU running a service

Sometimes you need to find all the computers on a domain that are running a certain particular service. By using Active Directory, supplying your canonical domain name, and define an output file, you can easily create a list of computers running a service.

First, start PowerShell as administrator, and import active-directory powershell components with the following command:

Import-Module ActiveDirectory

Then, open PowerShell ISE and copy in the following into a new .ps1 script:

$ou = "OU=Computers,OU=finance,DC=east,DC=contoso,DC=com"

$servers = Get-ADComputer -Filter * -SearchBase $ou | select-object 
-expandproperty name

Foreach ($server in $servers){
$Data = Get-Service -ServiceName *SAVService* -ComputerName $server | 
select machinename,name | sort machinename | format-table -AutoSize 

Write($Data) | Out-File .\machinesrunningSAVService.txt -Append
}

Run the script, and your output file will look similar to the following:

MachineName Name      
----------- ----      
hostname1   SAVService



MachineName Name      
----------- ----      
hostname2   SAVService



MachineName Name      
----------- ----      
hostname3   SAVService

How to enable RDP remotely with psexec pstools

If a computer is powered up on your network, but RDP is not enabled, you can create a group policy to enable RDP, and then restart the computer. Or instead, you can use psexec to remotely enable RDP.

Below are a couple one-line scripts to enable RDP on a remote computer from a different computer on the same domain. Keep in mind you need to be an administrator and you will only enable RDP for yourself, not an entire security group.

Download the pstools to your computer from the sysinternals download site here and unzip them into a folder named pstools at the root of your c: drive.
Open the command prompt as administrator.
Change directory into c:\pstools (where the pstools files are located) then run the command:

psexec64 -u domain\administrator -p "P@ssw0rd" \\remotecomputername.domain.com reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0

4. Run another command to open the required ports in the firewall on the remote machine

psexec64 -u domain\administrator -p "P@ssw0rd" \\remotecomputername.domain.com netsh firewall set service remoteadmin enable

5. RDP into the remote machine with mstsc.exe successfully, and that’s it!

Powershell – remotely copy multiple files to a list of computers

How to copy multiple files to a list of computers

PowerShell – copy a list of files to a list of multiple computers

Here is a simple PowerShell script I found (linked below) that can easily copy a list of files to a list of computers. If you want to copy more than one file to a lot of computers on your network, this simple script should work ok. It’s better to use a network share and use a UNC path to denote where the file source and destinations.

$a = Get-Content "C:\computerlist.txt" 

foreach ($i in $a) 

{$files= get-content "C:\fileslist.txt"
foreach ($file in $files)
{Copy-Item $file -Destination \\$i\C$\admin\ -force}
}

Here is a sample of what the computerlist.txt will look like:

hostname1.contoso.com
hostname2.contoso.com
hostname3.contoso.com

And here is a sample of what the fileslist.txt will look like:

\\fileserver\share\IT\myscript.ps1
\\fileserver\share\IT\Readme.txt
\\fileserver\share\IT\uninstall.bat
