Windows 2003 Scalable Networking Pack and Exchange connectivity

A few weeks ago the Exchange team posted a blog entry about Windows 2003 Scalable Networking pack and its possible effects on Exchange I figured this was an obscure thing and did not affect me, but it looks like I might be having this problem on one of my W2K3 SP2 / E2K3 SP2. Here are some possible issues from the Exchange Team blog:

• You cannot create a Remote Desktop Protocol (RDP) connection to the server.
  
• You cannot connect to shares on the server from a computer on the local area network.
  
• You cannot connect to Microsoft Exchange Server from a computer that is running Microsoft Outlook.
  
• You can only connect to Web sites that are hosted on the server or on the Internet by using a secure sockets layer (SSL) connection. In this scenario, you cannot connect to a Web site that does not use SSL encryption.
  
• You experience slow network performance.
  
• You cannot create an outgoing FTP connection from the server.
  
• You experience intermittent RPC communications failures.
  
• Some Outlook clients may be unable to connect to Exchange.
  
• You cannot run the Configure E-mail and Internet Connection Wizard successfully.
  
• Microsoft Internet Security and Acceleration (ISA) Server blocks RPC communications.
  
• You cannot browse Internet Information Services (IIS) Virtual Directories.
