ATA LightWeight Gatway causing RPC issues on DC while running RRS feed

  • Question

  • I have a customer evaluating Microsoft ATA 1.7 Update 2 in their environment.  The have deploy the ATA Collector and deployed a single ATA LightWeight Gateway on a single DC in the domain. It has been set as a domain synchronizer. However, after the service is running it is causing all sorts of authentication issues in the domain. We start seeing Event ID 5719 messages: The computer was not able to setup a secure session with a domain controller in domain X. The RPC Server is unavailable.

    Once we turn the service off the problem goes away.  The customer has halted the deployment/adoption until we can get this resolved. 

    NOTE: We did discover that time sync among the Domain Controllers was not working properly due to improper configuration (no external time source for PDCe and DCs that are VMs were using VMWare Tools and timesync from Hosts.  This time sync issue has been corrected and resolved.  Windows Firewalls are not running on DCs.

    What should we look at next?
