Explanation: After the NB-Java authentication service validates the user name on the logon dialog box for access, all Administration console service requests use an NB-Java user service. Communication between the Administration console and user service is tried to host (host) on the specified port number in the error message by using VNETD. (The NB-Java configuration option NBJAVA_CONNECT_OPTION is set to 1.) The NetBackup Administration Console log file should contain more detail about this error.
Recommended Action: Do the following, as appropriate:
On UNIX and Linux: Compare the VNETD entry in the /etc/services file with the VNETD_PORT entry in /usr/openv/java/nbj.conf
On Windows: Compare the VNETD entry with the VNETD_PORT entry in the install_path\java\setconf.bat file.
Ensure that no other application uses the port that is configured for VNETD.
