Problem

How to configure Backup Exec to use a TCP Port other than 3527 if that port is being used by another application.

 

Cause

TCP Port 3527 is reserved by Backup Exec. If this port is in use by another application, the installation will complete, but the Backup Exec Server Service will not start and Backup Exec will not load.

Locating the application using TCP Port 3527 and reassigning the application to another port is preferred; however, the port used by Backup Exec can be changed if necessary.

 

Solution

To change the port Backup Exec uses:

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
 
 
1. Using Regedit, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\veritas\Backup Exec For Windows\Backup Exec\Server.
 
2. Right click Server, select New and select DWORD Value.
 
3. Name the key MQPortID and enter the value of the new port that Backup Exec should use for communications. Refer figure 1.
 
Figure 1
 
 
Note: All MMS and CASO servers should be configured to use the same port that is assigned for MQPortID.
 
4. Restart Backup Exec's services

Note: the SBS firewall service uses port 3527 by default.
