WMS Anonymous User Authentication Plug-in Properties

The WMS Anonymous User Authentication plug-in grants all clients connecting to the server the same permissions as the Windows user account specified by the plug-in. For administration information about this plug-in, see Windows Media Services Help.

You can use the following properties on the IWMSAdminAnonUser interface to configure the plug-in.




Retrieves the name of the Windows user account that is used to specify access permissions when an anonymous user connects to a Windows Media server.


Retrieves a Boolean value indicating whether a password has been associated with anonymous user connections.

You can also use the following method.




Specifies a user name and password for the authorization process.

Using the IWMSAdminAnonUser interface is illustrated by the following examples.

Visual Basic .NET Example

Imports Microsoft.WindowsMediaServices.Interop 
Imports System.Runtime.InteropServices

Private Sub SetAnonPluginProps() 

' Declare variables.
Dim Server As WMSServer
Dim Plugin As IWMSPlugin
Dim AdminAnonUser As IWMSAdminAnonUser
Dim strUserName As String
Dim bPassword As Boolean

    ' Create a new WMSServer object.
    Server = New WMSServer()

    ' Retrieve the IWMSPlugin object for the 
    ' anonymous authentication plug-in.
    Plugin = Server.Authenticators.Item("WMS Anonymous User Authentication")

    ' Retrieve the administrative interface for the 
    ' anonymous authentication plug-in.
    AdminAnonUser = Plugin.CustomInterface()

    ' Retrieve the user name.
    strUserName = AdminAnonUser.AnonymousUserName

    ' Specify a new user name and password.
    bPassword = AdminAnonUser.IsPasswordSet
    If Not bPassword Then
AdminAnonUser.SetUserNamePassword("NewUserName", "NewPassword")
    End If
Catch excCom As COMException
    ' TODO: Handle COM exceptions.
Catch exc As Exception
    ' TODO: Handle exceptions here.
    ' TODO: Perform clean-up here.
End Try

End Sub  

C# Example

using Microsoft.WindowsMediaServices.Interop
using System.Runtime.InteropServices;

// Declare variables.
WMSServer Server;
IWMSPlugin Plugin;
IWMSAdminAnonUser AdminAnonUser;

    // Create a new WMSServer object.
    Server = new WMSServerClass();

    // Retrieve the IWMSPlugin object for the 
    // anonymous authentication plug-in.
    Plugin = Server.Authenticators["WMS Anonymous User Authentication"];

    // Retrieve the administrative interface for the 
    // anonymous authentication plug-in.
    AdminAnonUser = (IWMSAdminAnonUser)Plugin.CustomInterface;

    // Retrieve the user name.
    string strUserName = AdminAnonUser.AnonymousUserName;

    // Specify a new user name and password.
    bool bPassword = AdminAnonUser.IsPasswordSet;
    if (!bPassword)
        AdminAnonUser.SetUserNamePassword("NewUserName", "NewPassword");
catch (COMException comExc) {
    // TODO: Handle COM exceptions.
catch (Exception exc)
    // TODO: Handle exceptions here.
