    Hello, I created a test lab DSC Pull server using 'The DSC Book' / 3.0 OK
    However now am wanting to configure a newer release/use https

    So, configured a vanilla VM,
    Patched, Windows Server 2012 R2 standard
    Domain joined, admin rights, uac disable
    Installed WMF 5.0
    xPSDesiredStateConfiguration 5.0
    Generated self signed cert using script: https://gallery.technet.microsoft.com/scriptcenter/self-signed-certificate-5920a7c6
    Configured 'pullserver' MOF using msdn guide: https://msdn.microsoft.com/en-us/powershell/dsc/pullserver (+Also tried using the example config in the module itself)

    When i set the config/install i get 3 lines of errors below,
    on 2nd re-run no errors but the website is inaccessible: HTTP 503 Service Unavailable, both the pull site and the default site.

    Fixing Attempts:
    Rebuilt server same issue
    Getting same problem with 4.0 xPSDesiredStateConfiguration
    Installing IIS and DSC roles prior to mof deploy
    Trawling google/forums but haven't been able to solve whats going on..
    Turned on debug logging: wevtutil.exe set-log “Microsoft-Windows-Dsc/Analytic” /q:true /e:true
    Failed attempt number 1 : Couldn't delete file C:\Windows\System32\Configuration\DSCEngineCache.mof . The error code is 2. The error message is: The system cannot find the file specified.
    Have deleted these files from the configuration dir (with no luck), another post this worked for someone

    Having now spent 2 days trying to work this out, now I am reaching out, am i missing something simple?
    Any help muchly appreciated! 🙂

    May I ask why you're using a self signed certificate, which would be useless to clients?

  • #58757


    Hi Don,
    Its for a test environment lab (was planning to have this cert 'trusted root' on the clients).
    I dont have any CA cert's i can use. Is this likely part of the problem? I guess i can buy one.

    Did some tests with my selfsigned cert, added to the IIS 'default site', then import cert to client trusted root, this failed, still get cert warning on browsing, as you pointed out.
    I've always been a bit stand-offish when it comes to certificates and that jazz, ill look into setting up a CA in my domain and issue a certificate that way, give this another go tomorrow.

    It'd be far better to spin up a CA; the problem is that a self-signed certificate is only trusted by the machine that created it. It can't be readily used to create an HTTPS channel in a pull server, because none of the nodes contacting the pull server are going to trust the certificate. You do need a proper SSL certificate.

    You do also have some setup problems.

    VERBOSE: [PULL]:                            [[File]RegistrationKeyFile] The system cannot find the file specified.
    VERBOSE: [PULL]:                            [[File]RegistrationKeyFile] The related file/directory is: C:\Program Files\WindowsPowerShell\DscService\RegistrationKeys

    Is telling you that the pull server is missing its registration key file, which is required. Because this is happening during pull server setup, I'd surmise that it's unable to create the file you specified. You also have a conflict:

    RegistrationKeyPath = "$env:PROGRAMFILES\WindowsPowerShell\DscService"


    DestinationPath = "$env:ProgramFiles\WindowsPowerShell\DscService\RegistrationKeys.txt"

    You're setting up the file in one place, but telling pull server to find it in another place.

    You also appear to not have the correct certificate installed in the correct location:

    VERBOSE: [PULL]: [[xDSCWebService]PSDSCPullServer] Verify that the certificate with the provided thumbprint exists in CERT:\LocalMachine\MY\

    Pull server isn't able to find the certificate thumbprint you specified in the machine repository. Possibly you installed it in the wrong certificate store, or you provided the wrong thumbprint for it.

    Cheers Don, appreciate you taking the time to help out.

    I setup a CA, issued a certificate, left all other settings the same and looks OK!
    No red errors, https site access OK (from other clients too 🙂 )

    So it all came down to the certificate i was attempting to use.
    It referenced the correct thumbprint and was in the correct store, but something else was definitely wrong with it.

    Hi Ed,

    I am having a very similar problem, so I'm hoping you still read these forums and see this!

    How did you issue your certificate for your Pull Server, and how did you then import it on your Pull Server? I keep thinking I am doing it correctly but I get the same "specified logon" error you do 🙁



  • #83848



    Sure do.
    Make sure you use a cert trusted on the domain, not self signed certs. I did this by setting up the CA role on one of my servers.
    Then start the config from scratch with the new ca cert.
