I am utterly at a loss. There wasn't any spyware (as I thought there wouldn't be) - well, a bunch of semi-suspicious cookies, but that wouldn't really explain anything, and deleting them had no effect anyway. I deleted lots of invalid crap out of the registry. No dice. Norton claimed the drive was only 6% fragmented; Disk Defragmenter likewise said "this disk does not need defragmenting", but I tried anyway (despite having done so once before, about six weeks ago), thinking maybe Windows would like its own arrangement better, or something. No effect. I'm not sure how exactly to interpret netstat but all the IP addresses shown were local ones, almost all in the domain at that. Nothing looked suspicious to me. There's just nothing apparently wrong with it, yet it stil runs like crap.
I should add, if it wasn't clear already, that it's slow all the time, including before any user has logged on at startup, in between users when you log off and back on, and during shutdown as well (taking many seconds longer than the other one to shut down and power off, perhaps as much as two minutes more).
I give up.
