Moenchen; If all 3 have the identical version of windows, yes you can copy between the 3 computers - if not, you can use the SFC utility in many versions to restore it from the WIN9X distribution .CABs - In WIN98se it's in PRECOPY1.CAB from the CD. THe file is used to restore long file names in a MSBackup restore operation. Not exactly an essential component in most systems. G This hoax started in portugal & was translated a couple of times before it entered the English-speaking world. A good rule of thumb is if you get an EMail "warning" of this nature, that entreats you to forward to as many people as possible - DON'T! That's a tipoff that it was written by some prankster. Real alerts are NEVER distributed in this manner. If you feel compelled to warn friends, investigate at stiller.com or f-secure.com & if you find any truth to it, just forward the link with an brief explanation to your friends. This type of hoax is all the more dismaying, in that it depends on the good heart of folks who really want to be helpful to clog up the I-Net.
