I am trying to deploy Skype for Business 2015 to a test lab following this guide. I have performed all prerequisite actions up to Prepare Active Directory. when I run the task to prepare the AD schema from the Deployment Wizard it fails with the following error message in the log.
Error: Upload C:\Program Files\Skype for Business Server 2015\Deployment\Setup\ExternalSchema.ldf failed. The exit code is "5". ▼ Details └ Type: DeploymentException └ ▼ Stack Trace └ at Microsoft.Rtc.Management.Deployment.LcSchema.ThrowLDIFDE_ErrorCodeDeploymentException(String path, Int32 exitCode) at Microsoft.Rtc.Management.Deployment.LcSchema.UploadSchema(String path) at Microsoft.Rtc.Management.Deployment.LcSchema.PrepareSchema(String ldf, SchemaType schemaType) at Microsoft.Rtc.Management.Deployment.Tasks.ServerSchemaPrepareTask.Action()
I can confirm I am running as a member of the Schema Admins group.
