>The 2nd step of the Download of PO's is executed on a Windows XP Professional machine in Southern California; that machine has Service Pack 1 installed. We have Drive disconnections now that we didn't have before Sevice Pack 1 and our processes therefore fail, having depended on mapped drives to tables in the south and the north (of Calfornia). This whole process used to run perfectly.

Just curious, are you running a RAID system on the server? Or, could it be that the NIC or the cable would fail occasionnaly to that PC?
