New Skype for Business after failed Lync 2010 RRS feed

  • Question

  • I previously had a Lync 2010 environment but had a hardware failure and lost the CMS. Long story short, I used ADSI Edit to remove the RTC services under Configuration then removed all the Lync attributes from my users' accounts. I was then able to get all my users' accounts active with Skype for Business in Office 365.

    I now need to turn up Skype for Business 2015 with a mediation role so that I can connect my on-prem VoIP phone system to Exchange Online so I can move my users' UM-enabled mailboxes to EOL. I've spinned up a virtual server running Server 2016 and began the process of installing Skype for Business 2015. After the initial setup, the first screen of the Deployment Wizard indicates a warning under Prepare Active Directory: "Partial". When I click the Prepare Active Directory link, the Step 1 section indicates it's Complete. However, when I run Get-CsAdForest the following errors are returned.

    WARNING: The global object "RTC Service" in Active Directory is not ready.
    WARNING: The global object "" in Active Directory is not ready.
    WARNING: Forest is not prepped.
    LC_FORESTSETTINGS_STATE_NOTREADY
    WARNING: "Get-CsAdForest" processing has completed with warnings. "3" warnings were recorded during this run.
    WARNING: Detailed results can be found at
    "C:\Users\[SchemaAdmin]\AppData\Local\Temp\2\Get-CsAdForest-d1bb99f7-bdb1-4e22-9963-2a014e4a1120.html".

    The html file says the same thing. I do not know how to resolve this issue. Any guidance would be appreciated.

  • I'd try the last two steps from this article if you have the module installed: https://technet.microsoft.com/en-us/library/gg195815%28v=ocs.14%29.aspx?f=255&MSPPError=-2147217396 and try again.  Haven't been in this situation so not sure what the issue is.

  • Thank you for your reply. I ran both of those (Disable-CsAdDomain and Disable-CsAdForest) but still have the issue. I wonder if the configuration for Lync 2010 is stored in a different location than Skype wants it? I'm going to see if I can find a shell command to re-run the schema extension.

  • When I look in ADSI Edit under Schema, I verify the upper (1150) and lower (3) limits to be as documented. However, also in ADSI Edit under Configuration I see there is still no RTC Service listed, as the error is complaining. The way I understand it, I cannot do the Forest Prep without this. The saga continues...

  • When I ran everything from PowerShell, the commands completed successfully. I was waiting for replication between steps - even kicking off syncs in Sites and Services - but maybe it still just took a while to sync up. Regardless, I'm on to topology now. Thank you!
