On a client that is running Microsoft Windows 2000, you successfully install the Microsoft Intelligent Application Gateway (IAG) 2007 Service Pack 2 (SP2) client components. However, when you try to connect to the IAG Web site by using Windows Internet Explorer, Internet Explorer displays only a blank page and does not provide the logon page. Additionally, the status bar in Internet Explorer contains a message that states that the client components are not installed.
This problem occurs because of a change in IAG 2007 Service Pack 2 that enables non-Internet Explorer browsers and non-Windows-based clients to connect to IAG. However, after you install IAG 2007 Service Pack 2, an issue occurs when the legacy client components for Windows 2000 check the capability of the endpoint. The issue unexpectedly blocks Windows 2000 from successfully connecting.
To resolve this problem, install Update 1 for IAG 2007 Service Pack 2. For more information about Update 1 for IAG 2007 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:

You cannot install client endpoint components on a Windows 2000 client when the client is connected to the IAG portal. We recommend that you preinstall the client endpoint components by using the offline installation package that is provided with the IAG 2007 SP2 installation bits.
If Windows 2000 client components are not installed when a client is trying to connecting to the IAG portal, the endpoint user will not see the message that states that the client components are not installed. They will only see a blank page.
