The Microsoft® Exchange Server Analyzer Tool queries the CIM_Datafile Microsoft Windows® Management Instrumentation (WMI) class to determine the value that is set for the Version key of the Tcpip.sys file. If the Exchange Server Analyzer finds that the value for the Version key corresponds to a specific version of the Tcpip.sys file, the Exchange Server Analyzer displays a warning.
For more information about this warning, follow the recommendations in the Microsoft Knowledge Base article 898060, "Installing security update MS05-019 or Windows Server 2003 Service Pack 1 may cause network connectivity between clients and servers to fail" (http://go.microsoft.com/fwlink/?LinkId=3052&kbid=898060).
