Always prompt the user for a password.
fInheritColorDepth
Specifies whether the listener should use the color depth specified by the user. This member can be one of the following values.
0
Use the color depth specified by the server.
1
Use the color depth specified by the user.
ColorDepth
The color depth setting for the listener. This setting only applies when the fInheritColorDepth member is zero. This can be one of the following values.
1
8 bit
2
15 bit
3
16 bit
4
24 bit
5
32 bit
fInheritBrokenTimeoutSettings
Specifies whether the listener should use the BrokenTimeoutSettings value specified by the user. This member can be one of the following values.
0
Use the BrokenTimeoutSettings value specified by server.
1
Use the BrokenTimeoutSettings value specified by the user.
BrokenTimeoutSettings
The action the listener takes when a connection or idle timer expires, or when a connection is lost due to a connection error. This setting only applies when the fInheritBrokenTimeoutSettings member is zero. This member can be one of the following values.
0
When a connection or idle timer expires, or when a connection is lost due to a connection error, the user is disconnected but the session remains on the server.
1
When a connection or idle timer expires, or when a connection is lost due to a connection error, the session is terminated.
fDisablePrinterRedirection
Specifies whether printer redirection is disabled. This member can be one of the following values.
0
The user can enable printer redirection.
1
Printer redirection is disabled.
fDisableDriveRedirection
Specifies whether drive redirection is disabled. This member can be one of the following values.
0
The user can enable drive redirection.
1
Drive redirection is disabled.
fDisableComPortRedirection
Specifies whether COM port redirection is disabled. This member can be one of the following values.
0
The user can enable COM port redirection.
1
COM port redirection is disabled.
fDisableLPTPortRedirection
Specifies whether LPT port redirection is disabled. This member can be one of the following values.
0
The user can enable LPT port redirection.
1
LPT port redirection is disabled.
fDisableClipboardRedirection
Specifies whether clipboard redirection is disabled. This member can be one of the following values.
0
The user can enable clipboard redirection.
1
Clipboard redirection is disabled.
fDisableAudioRedirection
Specifies whether audio redirection is disabled. This member can be one of the following values.
0
The user can enable audio redirection.

Audio redirection is disabled.
fDisablePNPRedirection
Specifies whether Plug and Play redirection is disabled. This member can be one of the following values.
0
The user can enable Plug and Play redirection.
1
Plug and Play redirection is disabled.
fDisableDefaultMainClientPrinter
Specifies whether the client printer is the default printer. This member can be one of the following values.
0
The client printer is not the default printer.
1
The client printer is the default printer.
LanAdapter
The network adapter that the listener uses.
PortNumber
The port number of the listener.
fInheritShadowSettings
Specifies whether the listener should use the ShadowSettings value specified by the user. This member can be one of the following values.
0
Use the setting specified by the server.
1
Use the setting specified by the user.
ShadowSettings
The remote control setting for the listener. Remote control allows a user to remotely monitor the on-screen operations of another user. This setting only applies when the fInheritShadowSettings member is zero. This member can be one of the following values.
0
Remote control is disabled.
1
The user of remote control has full control of the user's session, with the user's permission.
2
The user of remote control has full control of the user's session; the user's permission is not required.
3
The user of remote control can view the session remotely, with the user's permission; the remote user cannot actively control the session.
4
The user of remote control can view the session remotely but not actively control the session; the user's permission is not required.
TimeoutSettingsConnection
The maximum connection duration, in milliseconds. Every time the user logs on, the timer is reset. A value of zero indicates that the connection timer is disabled.
TimeoutSettingsDisconnection
The maximum duration, in milliseconds, that a server retains a disconnected session before the logon is terminated. A value of zero indicates that the disconnection timer is disabled.
TimeoutSettingsIdle
The maximum idle time, in milliseconds. A value of zero indicates that the idle timer is disabled.
SecurityLayer
The security layer of the listener. This member can be one of the following values.
0
Remote Desktop Protocol (RDP) is used by the server and the client for authentication before a connection is established.
1
The server and the client negotiate the method for authentication before a connection is established.

Data sent from the client to the server is encrypted by using 56-bit encryption. Data sent from the server to the client is not encrypted.
2
All data sent from the client to the server and from the server to the client is encrypted by using the maximum key strength supported by the client.
3
All data sent from the client to the server and from the server to the client is encrypted by using 128-bit encryption. Clients that do not support this level of encryption cannot connect.
4

Remarks
Note
The wtsapi32.h header defines WTSLISTENERCONFIG as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
