SYMPTOMS
After you install Microsoft Windows XP Service Pack 1 (SP1), clicking About Windows Messenger on the Help menu in Microsoft Windows Messenger reports version 4.7. However, the Microsoft Exchange 2000 Instant Messaging Service client component is not updated.



CAUSE
This behavior occurs if you are using the Exchange 2000 Instant Messaging Service client. Windows XP SP1 includes version 4.7 of the Windows Messenger client for use with the online Microsoft .NET Messenger Service, but the Exchange 2000 Instant Messaging Service client is not included in SP1.



RESOLUTION
To complete the upgrade, download and install the latest Exchange 2000 Instant Messaging Service client. To do this, visit the following Microsoft Web site:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
Exchange 2000 Instant Messaging Service is a component of Microsoft Exchange 2000 that uses the Microsoft Active Directory directory service to provide additional security and identity controls that are critical to enterprise customers. Exchange 2000 Instant Messaging Service uses the same Microsoft Network (MSN) and Windows Messenger client interface as does the Microsoft .NET Messenger service, which is available online. However, with the MSN or the Windows Messenger client update for Exchange 2000 Instant Messaging Service, you can simultaneously connect to both the Microsoft .NET Messenger service and your corporate Exchange 2000 Instant Messaging Service.
