If you restored ePO - On-prem to a system with a new name or IP address, you must change the Agent Handler settings to connect to the restored server.
On the Agent Handler server, extract the ePO - On-prem software installation package to a temporary location.
In the extracted folder, open the Agent Handler folder, and double-click Setup.exe to start the Trellix Agent Handler InstallShield wizard.
Click Next to begin the change process.
From the Program Maintenance dialog box, select Modify to change which program features are installed, then click Next.
Configure these settings:
Type the restored system name of the ePO - On-prem server with which the Agent Handler must communicate.
Specify which port to use for Agent Handler-to-server communication. The default port is 8443.
Type the ePO Admin User Name and ePO Admin Password of a user with global administrator rights.
Click Next.
The installer contacts the ePO - On-prem server and obtains the details for the SQL Server hosting the ePO - On-prem database. The SQL Server and database details, except for the password, are already populated.
Enter the password for the account you specified and click Next.
Click Install to start the changes to the installation.
When installation is complete, click Finish.
Your Agent Handlers can now communicate with the restored ePO - On-prem server and SQL database.
