This section contains technical details of what technologies, firewall rules, or other prerequisites are required to enable a Site Manager Agent to communicate with the Site Manager server. This includes both normal communication and requirements for remote installation of the agent.

Agent Configuration Tool

The Agent Configuration Tool is installed with the Macrium Site Manager server and the Site Manager Agent.


Enable Remote Install

If 'Enable Remote Install' is clicked, the tool will open firewall settings for file & printer sharing as well as enable local account token filter policy, which is described in the section below: Troubleshooting Agent Communications v8.0#Enabling Remote Installation.

It is possible to enable the remote install via the command line: 

"C:\Program Files\Macrium\Agent\AgentConfigTool.exe" -SILENT_SETTING=YES -ENABLE_REMOTE_INSTALL=YES


Site Manager and the agent use a TCP/IP connection in order to communicate. 

TCP Port

This is the port used by Site Manager in order to accept an incoming TCP connection. This can be checked on the 'Agent' page of the Site Manager settings. Site Manager uses 51515 as the default port.

Connection Methods

The agent needs the IP (v4 or v6) of the machine that is running the Site Manager server. Alternatively, the agent will try to resolve to IP the DNS names or the NetBIOS of the machine.

Click the 'Add' button in order to add entries to the table.


Test the Connection

By clicking the 'Test' button the tool will attempt to connect to the Site Manager with all the specified connection methods. The results of the test will be reported in the table.


If at least one test in the table is reported as 'Successful' the agent will be able to connect to Site Manager.

If all the tests in the table are reported as 'Failed' check the section below.

Agent Configuration Tool is not able to Connect

If the connection tests in the table are reported as 'Failed', this may be due to a number of reasons: 

Incorrect Port

By default, Site Manager uses TCP port 51515 for communications. This can be changed in the settings of Site Manager. Confirm that the TCP Port in both the test tool and the Site Manager server match.

Failed Lookups

To connect DNS or NetBIOS names, the configuration tool/agent performs name lookups to resolve the name to an IP address. This uses both DNS and broadcast (LLMNR) lookups. To confirm that the lookups are working correctly, check the logs in C:\ProgramData\Macrium\SiteManager\AgentConfigTool.log  or attempt to ping the names directly using a Windows command line.

The firewall is blocking the connection 

Site Manager

The firewall of the machine hosting Site Manager must allow incoming TCP connections on the port specified in the Site Manager settings under the 'Server Connection Details' of the 'Agent' page. Site Manager uses 51515 as the default port.

Site Manager Agent

The firewall must allow outbound TCP traffic.

Enabling Remote Installation of the Agent on client computers

Computers connected to a domain

Site Manager's remote install mechanism uses file and print sharing' to perform remote installations. On most domains, this is enabled by default on all domain-joined computers. If there are additional restrictions on the network, remote installation will not work.

Computers not connected to a domain

Non-domain networks require additional steps to enable the appropriate services and functions required to remote install the Macrium Agent. Each client computer must be configured with the steps below to allow remote installation. 

These additional steps are only required for remote agent installation. If the agent is installed manually, these steps are not required.

Note that these steps are not required to manually install the Site Manager Agent. 

Enable File Sharing

In order to perform the installation, file and printer sharing must be turned on. This is found in the 'Network and Sharing Center', 'Advanced sharing settings' as shown below.


Enabling Remote Management Users

Outside a domain, users connecting to a computer remotely have reduced privileges. This is part of built-in Windows security measures. The reduced privileges mean that Local Administrator accounts do not have sufficient privileges to install the Site Manager Agent when connecting remotely.

To allow remote users to connect with their full administrator privileges, the following registry entry must be set on the client computer:
