We had that happen to us with NT systems and the 1668. Sometimes, it had to do with memory. We found that we had to use *very* specific SIMMS. Specially if they are 64MB SIMMS or above. They tended not to like EDO simms and preferred parity. Above 192MB, they almost always cause problems. It might be one of the reasons? Regards, Kedar.
