Session is Broken about sharepointdsc

[BrianFarnhill]

The clear remote sessions object is just used to ensure no existing remote sessions are interfering with the script. The error you are getting is insite of your xSPCreateFarm object, so it is nothing to do with the remote sessions one. Can you post your config file in full for me to look at?

I should have mentioned that I am using a DSC Pull Server to do the installation. Also, what is the rational fro having all set-target methods use Invoke-Command starting in xSPCreateFarm? Why not make the calls local? Because of the impersonnification?

[BrianFarnhill]

Yea its because we need to run the calls as a specific domain account that will have access to the databases. In regards to your setup, I think the issue is with your CredSSP configuration. You need to use FQDNs there and each machine needs to have itself listed as a delegate (as that is what we do, we open a 'remote' session to the local host as another user). So where you specify

DelegateComputers = "DSCPull"

try changing that to something like

DelegateComputers = "SharePoint.mydomain.local"

The reason our examples use a wildcard (such as *.mydomain.local) is so the SharePoint machines can all see each other, but if you want to lock it down specifying the current FQDN of the machine you are on will do. You can test the configuration by doing something like this:

Enter-PSSession -ComputerName $env:COMPUTERNAME -Credential (Get-Credential) -Authentication CredSSP

This is how we create the sessions, if that works and you get a valid session (using the credentials you have on InstallAccount) then the xSharePoint resources should all behave the same way.

[NikCharlebois]

Unfortunately, even if I use the FQDN is complains about my session being broken. Also, testing the config using CredSSP works fine

[NikCharlebois]

So to add to the confusion, the Error is thrown on the first "Invoke-Command" Line of the xSPCreateFarm resource:

Invoke-Command -Session $session -ArgumentList $PSBoundParameters -ScriptBlock {
$params = $args[0]
New-SPConfigurationDatabase -DatabaseName $params.FarmConfigDatabaseName -DatabaseServer $params.DatabaseServer
-Passphrase (ConvertTo-SecureString $params.Passphrase -AsPlainText -force) -FarmCredentials $params.FarmAccount
-SkipRegisterAsDistributedCacheHost:$true `
-AdministrationContentDatabaseName $params.AdminContentDatabaseName
}

But, both the config and the admin database are partially created on the SQL....

[BrianFarnhill]

OK I now have an environment that is replicating your issue. Leave it with me to troubleshoot on my end as well. I'll let you know how it goes

[BrianFarnhill]

Nik are you able to let me know a couple of things here?

• Are you running this with PowerShell 4 or 5?
• Are you running this one Azure virtual machines (specifically with the DSC VM extension)?

[NikCharlebois]

Hi Brian,

Thanks for following up. I am using PowerShell 5, April 2015 preview. My VMs are on premises, no DSC VM extension. Thanks

[BrianFarnhill]

This has been fixed by #60 and been pushed to the dev branch. I have a couple of other changes and fixes I want to roll in before I push it to the master branch and form a release though, so use the dev branch for the time being to resolve this issue.
