This document is a comprehensive list of the remote installation prerequisites you'll need for Network Discovery.

Overview

If you have experience and are well-versed in network monitoring and management, here's the overview of what you need to do: 

  1. You've entered valid domain admin credentials in the discovery profile with remote access rights,
  2. A domain controller is available on the network you've specified in the profile, and
  3. The target devices are domain-joined and the RPC port 135 is open. One way to accomplish this is by adding WMI to the “Allow apps to communicate through Windows Defender Firewall” list.

Detailed Remote Installation Prerequisites

To be able to install the Syncro agent remotely, you'll need to ensure the following prerequisites.

Remote Machine Requirements

  • The remote machine is accessible by IP address.
  • Remote machine admin’s credentials are provided.
  • The remote machine’s operating is Windows.

Configure User Permissions

  • User is a member of the Administrator and Distributed COM Users groups.
  • DCOM (for remote WMI access) is enabled (Run dcomcnfg from the Run dialog. Navigate to Component Services > Computers > My Computer). Right-click My Computer and select Properties. Go to the Default Properties tab).
  • Enable Distributed COM on the remote computer is checked.
  • Default Authentication Level is set to Connect.
  • Default Impersonation Level is set to Identify or higher.
