Netbackup Web Management Console

Hello Experts,

In our Windows 2008 R2 Master server NetBackup Web Management Console services are failing with an event ID.

EventID: 0x00001B58 (7000) - The NetBackup Web Management Console service failed to start due to the following error:

The service did not start due to a logon failure

What is this service and what is the use of it?

Thanks,

Hargyan
