    Tracy,

    Do check the release notes with the Redist package (as mentioned by Chip
    Andrews) or the SDK for info on the context that the .Net runtimes are
    running as by default. I believe that in Beta 2 they are running as SYSTEM
    by default but there are explicit instructions on changing this to a more
    appropriate user context. I don't have my notes here at home so I apologize
    for being a bit vague.

    John Alderson

    Subject: Microsoft .NET, ASP.NET, and IIS - any opinions?

    Greetings,

    We all know that IIS has it's flaws - and that for many of these there
    are
    patches available (or at least workarounds). However, with the immanent
    release of VisualStudio.NET and ASP.NET, I'm expecting to see installs
    of
    IIS and the .NET runtimes (which, if I understand it correctly,
    basically
    amounts to installing the full SDK - including command line compilers)
    on
    servers all over.

    And this begs the question - has anyone who has insight into this done
    any
    security studies on this combination? Is the addition of .NET to IIS
    going
    to cause any additional security holes (over and above those already
    present
    in IIS itself)? And are there recommendations for closing these types of
    holes if encountered?

    I already know I'm going to be asked to set up such a server, and I'd
    like
    to get a feel for what I'm letting myself in for. I know there are
    patches
    available for IIS (and I've already applied them to the IIS server we
    have
    live right now), but I'm curious if the addition of .NET to the mix is
    going
    to introduce new problems (and also interested in potential solutions to
    those problems while waiting for "official fixes" from Microsoft).

    Any takers?

    Tracy
