SYMPTOMS

When you try to use the Message.AuthenticationInfo.SecurityToken property in Microsoft Office Live Communications Server 2005, the Message.AuthenticationInfo.SecurityToken property returns the following result: IntPtr.Zero.

CAUSE

This issue occurs because access to the SecurityToken property of the Message.AuthenticationInfo property has been removed in Live Communications Server 2005. Therefore, when an application tries to access the SecurityToken property, a reference to the Microsoft .NET Framework Zero field, IntPtr.Zero, is returned to the application.

MORE INFORMATION
