    I don't think I've seen a posting or action of the Nimda worm to infect
    anything other than IIS.  I have over 500 Netscape servers on the net and
    none of them have had any problems.  Everything in the logs shows only IIS
    exploits.  Some of our IIS servers were infected, about 100, and we were
    able to clean them all with little to no problem without reformatting the
    systems.
    
    Has anyone seen anything similar to what Jim has seen?

    Something to bear in mind, and something that really tweaks me WRT how
    most folks seem to approach the whole Nimda issue:
    1. You don't need IIS installed to get infected with Nimda; it has no
    less than 5 other vectors to choose from
    2. Installing the IIS patches on a web server is not panacea to Nimda
    (see #1), just the issues that Nimda exploited
    3. The only absolute way to eradicate Nimda is to "nuke & pave" the
    infected host and rebuild it OFF THE NETWORK.
    
    Let's not discount the possibility that at least some of these requests
    are coming from hosts that are there for the express purpose of
    spreading Nimda and its ilk.  I know of at least two Verizon-based hosts
    that I've pointed out repeatedly only to see them remain on the 'net,
    spewing forth their infections requests.  If not for my ISA server, I
    too may have fallen prey to these insidious jerks.

    It's amazing to me when I see the amount of systems still infected with
    Nimda.  In today's logs I see a huge amount of systems in the ATT
    network that are still banging away.  I can't even give you the amount
    of systems that I'm seeing from China.  What is so difficult about
    patching your system against the .hta, .htq vuln.  I don't mean to go
    off on a rant but am I the only one that feels this way?  Is everyone
    else seeing the same activity?
