We are getting a rash of windows restarts in schools in Maine affecting all systems 98-XP. It appears to be like blaster ... but maybe a variant that can affect Win98? All are reporting that their anti-virus and MS security patches are up to date. We have a screenshot of the dialogue, but I do not think I can post a .jpg here, can I? Verbal description: It is a bright-red dialogue box with silver/gray trim that pops up saying "The computer will restart in [ ] seconds" with a long gray "cancel" button underneath. The [ ] is actually a small field box that will contain (randomly) the numbers 1-99. If you're sitting at the computer when it happens, you can actually cancel the restart. We're thinking is might also be a hacker sending RPC's to vulnerable random addresses in our state school system's intranetwork. Any ideas, comments, or clues would be appreciated. I can attach and send the jpg to anyone interested - email me: LBean@u47.k12.me.us
