The table below describes the parameters you can use to perform a silent installation of Backup Agent.
Changing the Backup Agent Port Number
Optionally, you can change the TCP port number that Backup Agent uses.
To change the Backup Agent port number
1. On the target DC, start Registry Editor (regedit.exe), and then locate and select the
HKLM\SYSTEM\CurrentControlSet\Services\ErdAgent registry key.
2. In the details pane, double-click the ImagePath value, and in the Value data text box,
specify the port number in the following way:
C:\WINDOWS\QuestRecoveryManager\ErdAgent.exe -I -P:3899
In this example, Backup Agent will use port 3899. When finished, click OK.
3. Close Registry Editor.
4. Restart the Quest Backup Agent service.
PARAMETER DESCRIPTION EXAMPLE
ERDPORT Specifies the target DC TCP
port number to be used for
Backup Agent traffic.
If this parameter is omitted,
TCP port 3843 is used by
default.
Msiexec /i "C:\Backupagent.msi"
ERDPORT=3355 /qn
FIREWALL_SETTINGS_CONFIGURE Specifies whether or not to
configure Windows Firewall on
a Windows Server 2008-based
target DC to allow Backup
Agent traffic.
You can use one of the
following values:
• 0. Specifies not to
configure Windows
Firewall on the target DC.
• 1. Specifies to
automatically configure
Windows Firewall on the
target DC.
Msiexec /i "C:\Backupagent.msi"

By default the silent installation process uses a local system account. To install Backup Agent on a
remote DC, this account must be given permissions to access that DC.
