This article describes how to change the port number used by the backup agent.
Recovery Manager allows you to back up Computer Collections using backup agents pre-installed on each target domain controller to be backed up.
To establish a connection to Recovery Manager, the backup agent uses the TCP port whose number is specified at the backup agent installation time.
To connect to a backup agent installed on a target domain controller, Recovery Manager uses the same TCP port. You can specify the port number with the Recovery Manager snap-in.
To change the backup agent port number, perform the following procedures.
On each target domain controller to be backed up, perform the following steps:
1. Start Registry Editor (regedit.exe), and then locate the 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, the backup agent will use the port 3899. When finished, click OK.
3. Close Registry Editor.
4. Restart the Quest backup agent service.
****WARNING: Using Registry Editor incorrectly can cause serious problems that can damage the operating system and the software installed. Quest cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.****
Start the Recovery Manager snap-in, and then perform the following steps:
1. In the console tree, select the node Recovery Manager for Active Directory, and then on the Action menu, click Settings.
2. On the General tab, select the Connect to the backup agent using the specific TCP port check box, and then specify the port number in the Port text box.
3. Click OK to close the Recovery Manager for Active Directory Properties dialog box.
Note If you have installed Microsoft Windows Firewall, the specified TCP port must be opened. You have to specify the same port number for all target domain controllers to be backed up.
