JSI Tip 6835. How do I prevent Windows Server 200x Terminal Services from announcing the service to TS clients?

Windows XP-based computers and Windows Server 2003-based computers with only Remote Desktop enabled do not advertise themselves as Terminal Services servers.

Windows Server 2003 Terminal Services-based servers and Windows 2000-based servers with Terminal Services, installed in either Application Server mode or in Remote Administration mode, advertise themselves as Terminal Services servers.

To prevent a Terminal Services-based computer from announcing itself to Terminal Services clients, but still appear as a server on the browse list:

1. Copy / Paste the following to a NoAnnounce.reg file:


\[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\]

2. Merge the NoAnnounce.reg file with the Terminal Services server's registry, or run regedit /s NoAnnounce.reg.

NOTE: This setting may prevent the server from being accessible by Terminal Services Manager.
