I know it's rather silly to reply on your on post, but I did some more research... It seems that our M$ using friends have some problems. Win2k/XP have a filesharing protocol on 445, and because most users of M$ products are so enlightend to choose a blank admin password, this is a security issue.
So apperently some ISP's have chosen to 'protect' their users from these attacks and are dropping these packets...
