Well, I thought my network was pretty safe from Blaster and Welchia. Software Update Services is pushing updates to the clients. Firewalls blocking the ports used by Blaster and Welchia, servier side and client side anti virus software catching Sobig other e-mail stuff. Everything having updates pushed to it...all was well in the world. Except that sales person's laptop that has been out of the office for who knows how long. It showed up today and starting Welchia activity. In no time at all, it had found the machines that had escaped Software Update Services. (Gasp, 3 machines!) Well, I know I'm doing better than other companies with only 3 infections that were quickly caught and the the conditions that allowed the infection corrected, but let that be a warning to others. Firewalling your network won't save you if you have devices moving between networks. Automatic updates are only good as long as you don't miss a box. Anti virus is only good when kept up to date... I'll take my small victory of only 3 machines vs the "we lost count" that other companies are dealing with. Andrew S.
