Error C0000006 is a general Windows failure that normally indicates that a connection has "dropped" unexpectedly. You can Google this error message to find details. It is not an Adagio problem.
However, we have seen this error in networks running XP SP2 and had it disappear when the workstations were move to SP3.
Are any of your workstations running XP at all? What server software are you running? Did you send us a snapshot as suggested in the last
Adagio KeyNotes?
