IMsTscNonScriptable interface

Contains properties and methods that relate to application of a password to the Remote Desktop ActiveX control.

The main use of the IMsTscNonScriptable interface is to configure automatic password logon access to Remote Desktop Session Host (RD Session Host) servers in scenarios where the Remote Desktop ActiveX control is hosted in a custom-written container. When automatic logon is configured, the user does not receive the Windows Logon dialog box at connection time.

On some platforms, the methods of the IMsTscNonScriptable interface can be used to specify passwords in one of three supported formats:

  • Plaintext
  • Portable encoded
  • Binary (nonportable) encoded

Note that a password in an encoded format consists of two parts:

  • Encoded password part.
  • Salt value part.

Both parts are required to set an encoded password. Neither the encoded password part nor the salt value part should be considered securely encrypted.

Scriptable access to plaintext passwords is available through the ClearTextPassword property of the scriptable interface IMsRdpClientAdvancedSettings.

The IMsTscNonScriptable interface can be accessed only through the vtable.


The IMsTscNonScriptable interface inherits from the IUnknown interface. IMsTscNonScriptable also has these types of members:


The IMsTscNonScriptable interface has these methods.

Method Description
ResetPassword Resets all password states in the control.


The IMsTscNonScriptable interface has these properties.

Property Access type Description
This property is not supported.
This property is not supported.
The Remote Desktop ActiveX control password, in plaintext format.
This property is not supported.
This property is not supported.


Providing a password to the Remote Desktop ActiveX control is optional. If you provide a password to the control, you should apply only one of the preceding three formats to the control before initiating the connection with a call to the Connect method.


You can also enable automatic logon at the server with the Remote Desktop Services configuration tool (Tscc.msc.) An administrator can use this tool to assign a specific password to a connection in a situation where an automated logon is necessary.
