Symptoms

  • Windows NetWorker Management Console (NMC) server.
  • NRE (NetWorker Runtime Environment) login failed with popup error:  "Unexpected Error Occurred. Check the logs"

Cause

NetWorker NMC GST (nmcdb) internal corruption.

Resolution

Option One:

Recover the nmcdb using the recoverpsm command: https://www.dell.com/support/kbdoc/000019968
This option will only be possible if nmcdb backups are completed:

Option Two:

Reinstall the NMC package with a fresh nmcdb. Using a new nmcdb will require reconfiguring any "NMC Roles" previously defined for local or external (AD/LDAP) accounts. Any NetWorker user accounts or external authorities previously configured will have been retained in the NetWorker authc server. Using a fresh nmcdb will also reset NMC "Reports" data.

1. Stop any NetWorker backups (if running).
NOTE: If the NMC server is installed on a different host than the NetWorker server, you will not need to stop backups.
2. Stop NetWorker services. 
net stop nsrexecd /y
3. Uninstall NetWorker NMC. This can be done one of two ways.
a. Uninstall the complete NetWorker package from Windows "Programs and Features." This does not delete any NetWorker database or configuration files.
b. Uninstall NMC using Windows wmic and sc command to only uninstall NMC package: https://www.dell.com/support/kbdoc/000203840
4. Rename the NMC installation folder; Default path C:\Program Files\EMC NetWorker\Management.
5. Install NetWorker NMC package again, this creates a new NMC installation folder and nmcdb.
