Lync 2010 install - Schema for child domain

Hi,

Im trying to install Lync2010 onto a child domain following the step by step guide on http://www.ocspedia.com/fe/Install_Microsoft_Lync_Server_2010.aspx?ArticleID=103 

In the instillation GUI when I run prepare schema it seems to be executing commands for the Parent domain:
Command: ldifde.exe -i -v -k -j "C:\Users\administrator.CHILDDOMAIN\AppData\Local\Temp\2" -f "C:\Program Files\Microsoft Lync Server 2010\Deployment\Setup\ExternalSchema.ldf" -c DC=X "DC=PARENTDomain,DC=internal" -s PD_DC-NAME.PARENTDomain.internal

ultimately when I run prepare current forest i get the following error message in the logs:

 SchemaValidationFailed: The topology XML is not a valid XML schema.
  SchemaValidationFailed: SCHEMA_VERSION_STATE_INVALID  
 SchemaValidationFailedResolution: Address the issues outlined in the logged validation errors.  
 Error: An error occurred: "Microsoft.Rtc.Management.Deployment.DeploymentException" "The schema is not ready. Cannot continue."

Anyone got experience on installing Lync on a child domain or any advice on this ?

Thanks

I've never installed this app, but any changes to the Schema needs to be on the Schema master.  The forest root will always hold this role, and not a child domain

thanks Vinchenzo-the-Second, that clears up that my first step was OK.
I've added a screen shot of the Log generated by running the Prepare Current forest in the GUI, which I believe should create security groups in the AD PrepareCurrentForrestError.pdf

Did you wait for replication to normalize after running the command in the Parent domain?
You can check the schema version in adsiedit to confirm if the schema was successfully replicated to all all DC's.

As mentioned above, your need to update the root then child domains when doing schema changes.
I have installed Lync in my organization and ran the wizard directly in the Parent Domain first without getting any errors.

Thanks, dvt Localboy, youre right, it took its time to replicate across to the child domain.

I do have a different error now:
Error: Computer is not a member of the root domain. For security reasons, this action must be run on a root domain computer.

Its because my server is in the Child domain - but this is where I want to install my Lync server, is this not possible? User generated image
