NetWorker: Unable to install NMC server software on Windows NetWorker server or dedicated NMC server

• The NetWorker Management Console (NMC) is installed (or being installed), on a Windows host.
• The installation wizard attempts to verify the NetWorker authentication server that is to be used for NetWorker authentication.
• The installation fails to validate the authentication server.

Unable to verify Authentication Server's hostname and/or port.

If you were prompted, but did not install the certificate, try again by selecting view certificate and installing it under root certification authority.

In no prompt was made for certificate validation, then verify that the NetWorker Authentication service is running on the configured host and port.

The NMC server can resolve the authentication server and connect to the authentication port (default 9090). Powershell command:

tnc AUTHC_HOSTNAME -p 9090

Manually installing the AUTHC server certificate does not resolve the problem: NMC: Installation Fails with Error "Unable to Verify Authentication Server's Hostname or Port"

The authentication server's authc-server.log shows:

• Linux: /nsr/authc/logs/authc-server.log
• Windows (Default): C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\logs\authc-server.log

ERROR Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceInitializer' defined in class path resource [serviceConfig.xml]: Invocation of init method failed; nested exception is org.h2.jdbc.JdbcSQLNonTransientConnectionException: Unsupported database file version or invalid file header in file "C:/Program Files/EMC NetWorker/nsr/authc-server/tomcat/data/authcdb.mv.db"

NetWorker AUTHC corruption. The specific error observed in the authc-server.log can occur if NetWorker is upgraded by performing an uninstall, then install of a new version, instead of using the "upgrade" option. The upgrade of the AUTHC files was not handled correctly by using this upgrade method.

Reinstall NetWorker with a new AUTHC folder to force it to replace the existing one.

These steps do not remove the NetWorker configuration or databases, there is no risk to historical backups.

1. Shut Down NetWorker: net stop nsrexecd /y
2. Uninstall NetWorker (and NMC, if on the same server)
3. Rename the C:\Program Files\EMC NetWorker\nsr\authc-server folder
4. Install NetWorker (this creates a new AUTHC configuration
5. Install NMC

Once complete, the services should start, and NMC login can be tested.
