Automatic Startup

By default, DW Blackjack® Servers are manufactured to automatically start the DW Spectrum Media Server and DW Spectrum Tray Assistant programs upon system startup. This is done with the assumption that the DW Blackjack unit will be solely used as a server for a DW Spectrum® system and to mitigate any unexpected downtime that the unit may experience in the event of sudden powerless.

In some rare cases, the DW Spectrum Media Server program may not start normally on a Windows or Ubuntu OS.  This is usually involving the Windows timeout utility that strictly runs all planned services after the operating system starts. However, if Windows cannot start a service in a timely manner, the service will be omitted by the OS.  Alternatively, this issue may also occur following a major OS update.  For example, upgrading from Ubuntu 14.04 to Ubuntu 16.04 or from Windows 7 to Windows 10.

This article will outline how to re-enable the DW Spectrum Media Server to automatically start upon system startup.

  • DW Blackjack® Cube™
  • DW Blackjack® P-Rack™
