How to change the default port used by the Backup Exec Remote Agent for Windows Servers (RAWS).


When a media server makes a connection with a remote system, the initial connection will be initiated on NDMP port 10000. The Remote Agent will be listening for connections on this pre-defined port.


In some situation if a conflict arises with the default NDMP port 10000 i.e. if port 10000 is used by another application or service and Backup Exec Job Engine service is unable to establish connection, the default port can be changed to another port number by modifying the services file located under <systemroot>\System32\Drivers\etc. Here, change the Network Data Management Protocol (NDMP) port to an alternate port number (Figure 1 and Figure 2).
Figure 1 :
Figure 2
To change the port to 9000, add an entry in the services file as follows: 
 ndmp 9000/tcp #Network Data Management Protocol
After adding the entry in the services file, save the file and restart Backup Exec services on media server and Remote agent service on particular remote server.

The steps given above must be performed on each remote machine being backed up, where port 10000 had a conflict. Windows 2008 and 2008 R2 may require a reboot after making change in the services file.

Additionally, in case if need to set the dynamic port range on Backup Exec, follow these steps:

To set the dynamic port range, perform the following :
  1. Select Tools  | Options
  2. On the Properties pane, under Job Defaults, click Network and Security
  3. Select the Enable remote agent TCP dynamic port range (49152 - 65535) check box and  specify a range of 25 or more ports. Sometimes, more ports will make the backup run faster.
