I am trying to Install windows security patches on a remote machine using powershell remoting. This is the function i am using to Update windows
<#
.SYNOPSIS
This functiion will automatically install all avaialable windows updates on a device and will automatically reboot if needed, after reboot, windows updates will continue to run until no more updates are available.
#>
function Install-WindowsUpdates
{
Install-Module -Name PSWindowsUpdate -RequiredVersion 2.1.0.1 -Force
Import-Module PSWindowsUpdate -Force
Get-WindowsUpdate -install -acceptall
}
When i run this function on a local host, the function is successful in installing windows security patches. I have the below script to do the same remotely:
param(
[Parameter(Mandatory = $true)]
[string] $IPaddress
)
try
{
$secpasswd = ConvertTo-SecureString "Pass@12345678" -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ("Admin02", $secpasswd)
#Create a Session.
$Session = New-PSSession -ComputerName $IPaddress -Credential $cred
cd C:\Users\Admin01\Documents
. .\Install-WindowsUpdates.ps1
Invoke-Command -Session $Session -ScriptBlock ${function:Install-WindowsUpdates}
return $true
}
catch
{
return $false
}
When i run this script i am getting the below error:
Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
+ CategoryInfo : NotSpecified: (:) [Get-WindowsUpdate], UnauthorizedAccessException
+ FullyQualifiedErrorId : System.UnauthorizedAccessException,PSWindowsUpdate.GetWindowsUpdate
+ PSComputerName : 10.0.0.7
I have setup both the loaclhost and remote machine for remoting and able to execute other scripts remotely. Also have enabled WMI on the remote machine. What other settings i have to do?
Using Scheduled Task: I am using the following script to start a scheduled task:
param(
[parameter(Mandatory = $true)]
[string]$IPaddress
)
$PSModulePath = $env:PSModulePath
$SplittedModulePath = $PSModulePath.Split(";")
$ModulePath = $SplittedModulePath[0]
$secpasswd = ConvertTo-SecureString "Pass@12345678" -AsPlainText -Force
$cred = New-Object System.Management.Automation.PSCredential ("Admin02", $secpasswd)
#Create a Session. Replace host name with the host name of the remote machine.
$Session = New-PSSession -ComputerName $IPaddress -Credential $cred
$User= "Admin02"
$Action= New-ScheduledTaskAction -Execute "PowerShell.exe" -Argument "$env:ALLUSERSPROFILE\Install-WindowsUpdate.ps1"
$Trigger= New-ScheduledTaskTrigger -At 5:05am -Once
Invoke-Command -Session $Session -ScriptBlock { Register-ScheduledTask -TaskName "Install-Updates" -User $Using:User -Action $Using:Action -Trigger $Using:Trigger -RunLevel Highest –Force }
I have copied the below script on the target machine at the path $env:ALLUSERSPROFILE
