I have the same symptoms on my HP t240a XP Home + NIS 2004 system.
Try this experiment:
1) Re-boot, leave Welcome screen showing for > 5 minutes, logon, NO
Scheduled Tasks will run at the appointed times (except for the one
NetDetect at user logon, but not the every 5 min. runs).
2) Re-boot, logon as soon as you see the Welcome screen, ALL Scheduled Tasks
will run at the appointed times.
But I can correct case (1) by Stop+Start of the Task Scheduler either via
Services or via Task Scheduler Advanced (BTW, they do slightly different
things).
I don't know whether this is a Task Scheduler or NetDetect problem.
