The only thing I could think of is my sister's iPod DSL connection wirer has been left in when the computer gets turned off. I'm not sure if this is the problem, but when the error came up again yesterday, the wire was left in.
Did you ever figure out what it was? I'm going crazy trying to figure this out, and just like you, it pops up each time I start windows.
Please let me know, i'll check back...
