Update - Thanks for all the good input from everyone. Nice to know you are all there in time of need (even if we couldn't solve the problem from the software side). I swapped out the mobo, went from an AOpen MX46VG(E) to an AOpen AX4SPE-UN. Same CPU, RAM, NIC, SCSI, DAT - went from on board video to a GeForce MX4000 8x AGP. Said the magic word: Abra-ca-pocus! and the problem dissapeared. Ralph Eagle Kubinski Business Systems
