One of the most often requested ‘tweaks’ for a Citrix or Terminal Services environment is to disable the console beep that annoys users when a dialog box appears in a session.

Its relatively easy to do but does require two different configuration items and a reboot of the Terminal Server.  The first configuration item involves disabling the beep hardware object.

• First open the device manager.
• From the View menu select “Show Hidden Devices”
• Navigate to Non-Plug and Play Drivers > Beep
• Disable the Beep device

The second part of this configuration is a simple registry edit.

• HKLM\System\CurrentControlSet\Control\Terminal Server\DisableBeep = 1

Now all thats left is a reboot.  That should get rid of that annoying beep once and for all!
