    Phillip, your explanation of the problem is quite clear and very
    understandable, and as Andrew stated, it is a CRAZY flaw that ISA2004 has to
    work out.

    Were you able to reproduce this error on your system, just to eliminate the
    fact that it could be misconfiguration on my part?

    Thanks again for the explanation. The good thing is that in my network, I
    had given EVERY device attached a NetBIOS name, so I'm cool for now :)
    (lucky me). But MS needs to address this.
