Since upgrading to NVBU 10, the NetVault server generates multiple error messages in the Windows Event Logs:
Error ID 4103:
"Fatal error during address bind (Port 80) Permission denied".
However backup and restore compelete successfully.
The use of Port 80 indicates the NetVault Web Service configuration is using the HTTP protocol.
There are 2 methods to enable web service in NVBU: over HTTP and HTTPS.
Unfortunately as port 80/HTTP is a popular port, it may already be used by other applications.
Open nvconfiguration on the NetVault server and go to the Web Service tab.
Make sure the Enable Web Service over HTTP option is disabled.
Ensure the Enable Web Service over HTTPS is selected.
HTTPS is the preferred protocol. It provides encrypted communication between the clients and the server, which protects sensitive data such as NetVault Backup passwords passed between the browser and NetVault Web Service.
If HTTP is required, the default HTTP port is 80 and is often used by many other applications. If this is the case, configure an alternate port to allow successful bind and prevent these errors from happening.
