Windows / Microsoft AD Context Logs - Computer Accounts script needed

Howdy,

I am facing some challenges with acquiring OnPrem AD Contextual data.

Get-ADUser works fine, but the Get-ADComputer part errors out

Using this:

https://docs.cloud.google.com/chronicle/docs/ingestion/default-parsers/windows-ad

# Set the location where the log file will be written
$OUTPUT_FILENAME “C:\Data\SecOps\Logs\AD-AssetContext.json"

If (Test-Path -Path $OUTPUT_FILENAME) { Remove-Item -path $OUTPUT_FILENAME -ErrorAction SilentlyContinue}

# USER_CONTEXT: Gets all Active Directory users and their properties.
Get-ADUser -Filter * -properties samAccountName | % { Get-ADUser $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }

# ASSET_CONTEXT: Gets all Active Directory assets and their properties.
Get-ADComputer -Filter * -properties samAccountName | % { Get-ADComputer $_.SamAccountName -properties * | ConvertTo-JSON -compress | Out-File -encoding utf8 $OUTPUT_FILENAME -Append }

This errors out with 

Get-ADComputer : The server has returned the following error: invalid enumeration context.
At C:\Data\SecOps\AD-AssetContext.ps1:44 char:1

    + CategoryInfo          : NotSpecified: (:) [Get-ADComputer], ADException
    + FullyQualifiedErrorId : ActiveDirectoryServer:0,Microsoft.ActiveDirectory.Management.Commands.GetADComputer 

We believe this is due to the session timing out.

We have a lot of computer accounts in our AD.

Thank you in advance.
