I have used the DOMAINAdministrator account is used for the credentials to run the below PowerShell script to scan for Expired SSL certificate:

$ScriptBlock = {

    Get-ChildItem Cert:*My -Recurse |

        Select-Object Subject, 

        DnsNameList, 

        NotAfter, 

        NotBefore, 

        Thumbprint, 

        Issuer,

        @{n = "SAN"; e = {Try {($_.Extensions | Where-Object {$_.Oid.Value -eq '2.5.29.17'}).Format(0)} Catch {} }},

        @{n = "IsValid"; e = {$today = Get-Date; If ( $_.NotBefore -lt $today -and $_.NotAfter -gt $today ) { $true } Else {$false} } } }



$computers = Get-ADComputer -Filter {Enabled -eq $True -and OperatingSystem -like "*Server*"} -SearchBase "OU=Servers,OU=Production Site 1,DC=Domain,DC=com" | 

                Where-Object {Test-Connection $_.Name -Count 1 -Quiet} | 

                Select-Object -expandProperty DnsHostName | 

                Export-Csv -Path C:LogsSSL.csv -NoTypeInformation



$adCred = Get-Credential Invoke-Command -ComputerName $computers

-ScriptBlock $ScriptBlock -Credential $adCred

But, then I got the error:

[Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData]
Connecting to remote server
Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData failed
with the following error message : WinRM cannot process the request.
The following error occurred while using Kerberos authentication:
Cannot find the computer
Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData. Verify
that the computer exists on the network and that the name provided is
spelled correctly. For more information, see the
about_Remote_Troubleshooting Help topic.
+ CategoryInfo : OpenError: (Microsoft.Power...FormatEntryData:String) , PSRemotingTransportException
+ FullyQualifiedErrorId : NetworkPathNotFound,PSSessionStateBroken

How to fix it so I can get the CSV result?

The updated error code is now:

Invoke-Command : Cannot validate argument on parameter 'ComputerName'.
The argument is null or empty. Provide an argument that is not null or
empty, and then try the command again. At line:19 char:30
+ Invoke-Command -ComputerName $computers -ScriptBlock $ScriptBlock -Cr ...
+ ~~~~~~~~~~
+ CategoryInfo : InvalidData: (:) [Invoke-Command], ParameterBindingValidationException
+ FullyQualifiedErrorId : ParameterArgumentValidationError,Microsoft.PowerShell.Commands.InvokeCommandCommand

This line is incorrect for a start

$computers = Get-ADComputer -Filter {Enabled -eq $True} -SearchBase "OU=Servers,OU=Production,DC=Domain,DC=com" | Select-Object -expandProperty DnsHostName | Select-Object -expandProperty DnsHostName | Export-Csv -Path C:LogsSSL.csv -NoTypeInformation

Should be

$computers = Get-ADComputer -Filter {Enabled -eq $True} -SearchBase "OU=Servers,OU=Production,DC=Domain,DC=com" | Select-Object -expandProperty DnsHostName | Export-Csv -Path C:LogsSSL.csv -NoTypeInformation
