AD Forest Sync

Hey everybody,

I try to set up an AD Forest Sync to Sync our Production and Test environment AD.

I have created two different Workflows with Connections and Mapping Pairs.

The Update Workflow is working without any problems.

But the Provisioning Workflow, to create new Users is facing a problem. At the end of the Workflow there is the error that the RPC Server is unavaible, but the Domain Controller in Test is up and running and the firewall does not shows anything up.

Can someone help me?

Kind regards
