I think you need to read a little more carefully and also see http://support.microsoft.com/default.aspx?scid=kb;en-us;Q262631 Which is linked to the article you mention. The only real downside is that you can't change the "level-1" list at all unless you use Outlook 2K in and Exchange server environment, with your mail delivered to an Exchange mailbox, then it can be changed by and admin. IMHO all the file extensions that I see on the "Level-1" list belong there anyway. If you need to e-mail one of those files for some reason (ie, sharing development code or whatever), just zip it and then send it.... Now back to more operational content......? /Alex Kiwerski -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Al Rowland Sent: Thursday, September 19, 2002 10:12 AM To: 'Mike Lewinski'; nanog@merit.edu Subject: RE: download.microsoft.com problem Don't know the history of this input but MS is in the process of an auto security update for ALL XP machines worldwide. Might have something to do with this behavior. On a side note, it kills ALL E-mail attachments (MS files et al) and significant web content. Security vulnerability in XP. As I told the MS agent I talked to, kind of makes Windows useless. :) http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q265424 Best regards, _________________________ Alan Rowland Also an ATT BI customer.
