Error description

  • When using the IBM Rational ClearCase MultiSite shipping server
    in a firewall-enabled configuration with strict outbound port
    allocation on Microsoft Windows 2008 R2 Server, connection
    errors may occur, causing hosts to be incorrectly flagged as
    down.
    
    This issue is caused by a new Windows Sockets behavior in the
    most recent version of Microsoft Windows.
    
    The current workarounds are:
    1) Do not use MSSHP_STRICT port allocation.
    2) Use a Unix or Linux host to provide firewall-compatible
    shipping server services.
