Repository Unavailable to Veeam Agent for Microsoft Windows Installed on a Veeam Backup and Replication Server

KB ID: 2403
Product: Veeam Agent for Microsoft Windows
Version: 2.x
Last Modified: 2017-11-21


The behavior described here can be observed in the following configuration:

- multiple installations of Veeam Agent for Microsoft Windows (VAW) are targeted at a Veeam Backup and Replication (VBR) repository within the same domain;
- all VAW-processed computers are added to an AD computer group;
- the mentioned group is used to manage Agent Backup Permissions to access the repository.

This configuration works fine for all VAW installation except the one on the VBR server.


During the authentication on the same machine, Kerberos authentication is not used, thus making the repository unavailable for the local installation of VAW.


A group which contains NT AUTHORITY\SYSTEM account should be added to the Agents Backup Permissions.

By default, the BUILTIN\Administrators group contains the Local System account.
