Hi ,i have created a dsc https pull server and the https website working fine but when i am trying to update the configuration on a bode using update-dscconfiguration it throws an error

my code is:

[DSCLocalConfigurationManager()]
Configuration LCM_HTTPSPULL
{
param
(
[Parameter(Mandatory=$true)]
[string]$ComputerName,

[Parameter(Mandatory=$true)]
[string]$guid

)
Node $ComputerName {

Settings {

AllowModuleOverwrite = $True
ConfigurationMode = ‘ApplyAndAutoCorrect’
RefreshMode = ‘Pull’
ConfigurationID = $guid
}

ConfigurationRepositoryWeb DSCHTTPS {
ServerURL = ’ https://win-1c1g3jjmvte.company.com:8080/PSDSCPullServer.svc/ ’
CertificateID = ‘535ce718e45636f4f85faa27bb4820ddcd4d0196’
AllowUnsecureConnection = $False
}
}
}

Computer list

$ComputerName=‘2nd-server’

Create Guid for the computers

$guid=[guid]::NewGuid()

Create the Computer.Meta.Mof in folder

LCM_HTTPSPULL -ComputerName $ComputerName -Guid $guid -OutputPath c:\DSC\HTTPS
Set-DscLocalConfigurationManager -ComputerName 2nd-server -Path c:\dsc\https -Verbose

configuration SMTP {

Node HTTPSComputers {

WindowsFeature SMTP{
Name = ‘SMTP-Server’
Ensure = ‘Absent’
}
}
}

SMTP -OutputPath C:\DSC\HTTPS

$guid = Get-DscLocalConfigurationManager -CimSession 2nd-server | Select-Object -ExpandProperty ConfigurationId
$source = “C:\DSC\HTTPS\HTTPSComputers.mof”
$dest = “C:\Program Files\WindowsPowerShell\DscService\Configuration$guid.mof”
Copy-Item -Path $source -Destination $dest
New-DscChecksum $dest
Get-WindowsFeature -ComputerName 2nd-server -Name smtp
Update-DscConfiguration -ComputerName 2nd-server -Verbose -Wait

but the error comes up:

As @alexw suggests, formating the outpout would make it easier to see.

It looks like the checksum files are not valid,.

Check they following two lines are doing what you expect:

Copy-Item -Path $source -Destination $dest
New-DscChecksum $dest
