I’ve added DSL and Norton Internet Security (software firewall) to my system and noted times when the system seems more i/o bound than in the past. The system is an 800 Mhz Pentium III with 128 MB memory and has never limped in the past. For the first time I’ve seen it fail to buffer characters during incoming mail, etc. I’ve seen the system go through periodic lock-ups more often and tend to think Win 2000 has grown unstable. Anyone have any ideas as to what to do to “clean up” Win 2000, or is this tied to the way Win 2000 handles I/O with DSL?
