Applications :: ITunes Unknown Error (-3237) On Vista Desktop?

I just recently had an iTunes Unknown Error -3237 on my Windows Vista Desktop. My iPhone and iTouch doesn't appear in iTunes but show up in My Computer. I plugged it into my sisters Toshiba laptop and it is detected just fine. I plugged it into my MBP and it is detected fine as well. I don't know what the issue is for iTunes. I am running iTunes 8.1. My iPhone is synced with that computer and now I can't sync music to it in fear of losing the current ones I have on my phone. Also I get a iTunes Store error as well.

It won't let me onto the iTunes Store. It just comes up with an error saying there is a network issue to to check it. My internet is working fine but I can't figure out why iTunes is freaking out on me ~_~. iTunes Store works fine on my MBP and sister's laptop. My iPhone backups are all on that computer and same for my applications that aren't on my phone. I have tried reinstalling iTunes and it doesn't remedy the issue. I tried turning off iPod Services and starting it back up to no avail.
