Cause

If only the Windows Admin Console is installed onto a workstation, the

HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup\CurrentVersion\Config EMMSERVER registry key is not created during the Netbackup Windows Remote Admin Console installation.

 

Solution

Adding/changing the EMMSERVER REG_SZ entry to point to any working NetBackup Master that this Remote Admin client (RAC) has a "SERVER = " entry in the bp.conf file.
Create following registry key on the server or workstation where RAC has been installed: HKEY_LOCAL_MACHINE\SOFTWARE\Veritas\NetBackup\CurrentVersion\Config\EMMSERVER (of type = REG_SZ) and add the name of any working NetBackup Master server in the environment to which you want to connect.

Applies To
