Running DSC labs, and yesterday I set up DSC Pull server nr 3 (DSC03) according to my documentation. Windows 2012 R2, Full Windows Update and:
Add-WindowsFeature Dsc-Service
winrm quickconfig
& ‘C:\Filer\Windows Management Framework 5.0 ProdPreview\Win8.1AndW2K12R2-KB3066437-x64.msu’
Find-DscResource -moduleName xPSDesiredStateConfiguration
Install-Module xPSDesiredStateConfiguration -Verbose
Everything as expected.
Then I was support to configure DSC Pull service, and…
`

Googling some of the keywords gives me nothing, like $notAllowedValue.
The configuration is pretty simple, it is standard “copy-paste code” from the net.
`
configuration NewPullServer
{
param ( [string]$ComputerName = ‘localhost’ )
Import-DSCResource -ModuleName xPSDesiredStateConfiguration
#Import-DscResource –ModuleName ‘PSDesiredStateConfiguration’
```
Node $ComputerName
{
WindowsFeature DSCServiceFeature
{
Ensure = “Present”
Name = “DSC-Service”
}
xDscWebService PSDSCPullServer
{
Ensure = “Present”
EndpointName = “PSDSCPullServer”
Port = 8080
PhysicalPath = “$env:SystemDrive\inetpub\wwwroot\PSDSCPullServer”
CertificateThumbPrint = “AllowUnencryptedTraffic”
ModulePath = “$env:PROGRAMFILES\WindowsPowerShell\DscService\Modules”
ConfigurationPath = “$env:PROGRAMFILES\WindowsPowerShell\DscService\Configuration”
State = “Started”
DependsOn = “[WindowsFeature]DSCServiceFeature”
}
xDscWebService PSDSCComplianceServer
{
Ensure = “Present”
EndpointName = “PSDSCComplianceServer”
Port = 9080
PhysicalPath = “$env:SystemDrive\inetpub\wwwroot\PSDSCComplianceServer”
CertificateThumbPrint = “AllowUnencryptedTraffic”
State = “Started”
IsComplianceServer = $true
DependsOn = (“[WindowsFeature]DSCServiceFeature”,”[xDSCWebService]PSDSCPullServer”)
}
}
```
}
#This line actually calls the function above to create the MOF file.
NewPullServer –ComputerName dsc03 -OutputPath ‘C:\DSC\DSC Server’
#Start-DscConfiguration -Path 'C:\DSC\DSC Server' –Wait -Verbose
#Start-Process -FilePath [http://dsc03:8080/PSDSCPullServer.svc/](http://dsc03:8080/PSDSCPullServer.svc/)
`
I am pretty lost here. I guess it is a really simple error, but I cannot find it.
Any ideas?

Forgot one important thing. …
I can run this config on DSC01 / DSC02, no errors.
In fact, true copy and paste, run. No errors.

I haven’t been able to find any reference to that variable in the PSDesiredStateConfiguration or xPSDesiredStateConfiguration modules; not sure where it’s coming from. In any case, the error looks like something that would come up with StrictMode has been turned on. Try running Set-StrictMode -Off , and then running the code again to see if it makes any difference.

No clue what happend here, but the error is resolved now.
Changes:
- Moved the server to a new OU.
not really a big difference, but some GPO’s are different.
Maybe StrictMode is effected (?) and I know Windows Update settings are different. (Option to bypass WSUS).
- Rebooted.
Fixed.
Checked Windows Update logs, no new stuff there…
Honest: Strange… Wish I had the time to investigate this.

Hello,
I have just made a test with Windows 2012 and WMF 5 production preview and I confirm the Dave’s solution, the problem is with Set-StrictMode. You have to turn off (Set-StrictMode -Off) before “Configuration” block.
Regards,
