Uninstall software from multiple computers

Posted on 9 November 2016 by Albert van Boerum Leave a comment

To uninstall software from multiple computers you must determine the name of the software you want to uninstall.

Get the list of installed applications from a computer:

Get-WmiObject -Class Win32_Product | select name

1	Get-WmiObject -Class Win32_Product \| select name

If you want to see the programs on a remote computer user the -computername option.

Find the program you want to uninstall, for example “Sophos Patch Agent” from 3 computers:

$collection = 'wks001','wks002','wks003'
foreach ($item in $collection)
{
    $app =  Get-WmiObject -Class Win32_Product -Filter "Name = 'Sophos Patch Agent'" -ComputerName $item
    $app.Uninstall() 
}

$collection = 'wks001','wks002','wks003'

foreach ($item in $collection)

{

$app = Get-WmiObject -Class Win32_Product -Filter "Name = 'Sophos Patch Agent'" -ComputerName $item

$app.Uninstall()

}

This will uninstall the software (one at a time) from the computers.

Install software on multiple computers simultaneous

Posted on 31 October 2016 by Albert van Boerum Leave a comment

Install software on multiple computers simultaneous.

Also, first make sure the server from which you install the software accepts the CredSSP connection.

icm { Enable-WSManCredSSP -Role Server -Force} -ComputerName NameOfTheServer

1	icm { Enable-WSManCredSSP -Role Server -Force} -ComputerName NameOfTheServer

You need to use CredSSP for authentication because Powershell has a build-in protection against multi-hop use.

Run the next code to install the software.

$cred = Get-Credential
$allpcs = Get-ADComputer -Filter {(Name -like "wks*") -and (enabled -eq "true")}  | Select-Object -expand Name

Enable-WSManCredSSP -Role client -DelegateComputer $allepcs -Force
icm {\\server\share\Setup.exe} -Computer $allpcs -Authentication Credssp -Credential $cred

$cred = Get-Credential

$allpcs = Get-ADComputer -Filter {(Name -like "wks*") -and (enabled -eq "true")} | Select-Object -expand Name

Enable-WSManCredSSP -Role client -DelegateComputer $allepcs -Force

icm {\\server\share\Setup.exe} -Computer $allpcs -Authentication Credssp -Credential $cred

Remove old logfiles from Exchange servers

Posted on 20 April 2015 by Albert van Boerum Leave a comment

You can use Powershell to remove old logfiles from exchange servers. Those logfiles are located on the Client Access Servers (CAS servers) in the inetpub folders.

To remove the files older then 60 days use this script.

Fill in your own CAS servers on the variable $servers line. You can use as many as you want to.

# delete old logfiles from Exchange CAS servers
$servers = 'CASServer1','Casserver2'
foreach ($server in $servers) {
    $FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"
    Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force
}

# delete old logfiles from Exchange CAS servers

$servers = 'CASServer1','Casserver2'

foreach ($server in $servers) {

$FromPath = "\\$server\c$\inetpub\logs\LogFiles\W3SVC1"

Get-ChildItem $FromPath -File| Where-Object { $_.lastwritetime -lt (get-date).Adddays(-60) } | Remove-Item -Force

}

Check a service on alle servers

Posted on 8 April 2015 by Albert van Boerum 2 comments

You can use this script when you want to check multiple servers for the status of a service.

This script gets all the servers from the AD and test is they are available. Next it checks if there is a service with the name backupexecagent* and then displays the status.

The script below is not the most efficient script but it does the trick.

$servers = Get-ADComputer -Filter 'operatingsystem -like "*server*"' | Where-Object -Property enabled -EQ "$true"  


foreach ($server in $servers)
{
if (Test-Connection -ComputerName $server.Name -count 1 -Quiet) {
    if (get-service -ComputerName $server.name -Name BackupExecAgent* -ErrorAction SilentlyContinue)  
        {
            Get-Service -ComputerName $server.name -Name BackupExecAgent*  |select-object machinename,status,Displayname 
        }
    } 
}

$servers = Get-ADComputer -Filter 'operatingsystem -like "*server*"' | Where-Object -Property enabled -EQ "$true"

foreach ($server in $servers)

{

if (Test-Connection -ComputerName $server.Name -count 1 -Quiet) {

if (get-service -ComputerName $server.name -Name BackupExecAgent* -ErrorAction SilentlyContinue)

{

Get-Service -ComputerName $server.name -Name BackupExecAgent* |select-object machinename,status,Displayname

}

If someone knows how to make this run faster… please let me know.

Check service startup type and status with Powershell

Posted on 10 March 2015 by Albert van Boerum Leave a comment

A powershell code to check a specific service on a computer and tells you what the startup-type is (Auto, disabled, manual) and what the current state is of the service.

$strComputer = read-host "Computername"
$strService = read-host "Servicename"

$svc = (get-wmiobject -class win32_service -filter "name='$strService'" -computername $strComputer)
Write-Host "On computer $strComputer the service: $StrService Startup Type is" $svc.startmode "and is" $svc.state

$strComputer = read-host "Computername"

$strService = read-host "Servicename"

$svc = (get-wmiobject -class win32_service -filter "name='$strService'" -computername $strComputer)

Write-Host "On computer $strComputer the service: $StrService Startup Type is" $svc.startmode "and is" $svc.state
