Silly issue… actually. It won’t be a problem that keeps you from working, though if your not used to hearing it it might drive you mad! After our recent upgrade to Windows 2003 (for Terminal Services) and Citrix Presentation Server 4, users kept complaining about a “beep” that would happen all the time. For example, if you were going to close a Microsoft Word document without saving it you would hear a “beep” sound when the message box pops up.

It’s a fairly easy fix and you can deploy it a number of ways. Modify the following key on the Terminal Services server using regedit:
[HKEY_CURRENT_USER\Control Panel\Sound]
“Beep”=”no”
“ExtendSounds”=”no”

Now since this is a registry setting for the current user you will have to have it applied to all users who use this system. Now I did this by making a simple reg file and referencing it in a bat file that I put in the “All Users\Start Menu\Programs\Startup.” Users will have to log on & off …then back on… to notice the change but still…no beeping.

Also to make this effective for new users either just keep the bat file there forever or change the same keys in this location:
[HKEY_USERS\.DEFAULT\Control Panel\Sound]

Hope this helps someone.
