How to configure Backup Exec to use a TCP Port other than 3527 if that port is being used by another application.
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.
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.
Note: SBS 2000 and SBS 2003 install the SBS firewall service on port 3527 by default.
