In Windows Server 2008, only servers that have Terminal Server role service installed will advertise themselves as Terminal Servers, and will be viewable in the Terminal Services Manager snap-in.
A client computer running, Remote Desktop Client obtains the list of only the Terminal Servers. It uses an API Call (NetServerEnum) with a parameter for server type (SV_TYPE_TERMINALSERVER). The Terminal Server computer responds as per the value set in the registry entry. The value is stored in the TSAdvertise registry entry at HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Terminal Server key.
You can change the value of TSAdvertise entry to enable/disable the advertising of Terminal Server computer.
- 0 = Disable Advertising
- 1 = Enable Advertising
