The time seemed to be close enough... Shouldn't the Windows XP SNTP client be good enough? It works fine on other computers.
Anyhow, while I wonder what went wrong for my own curiousity, I don't want to continue stealing the other person's thread. I also don't frequently go to the other person's house and wont be spending hours to use their working computer just to figure out the problem (kinda insulting to them :-) )
Thanks again to all.
