At first was speculating that an issue was with some interuption in the network since we experienced some severe storms ect. Server is protected quite well and I am having a problem trying to figure out what is causing these errors. It is not consistent with a particular table, just that it always is a Memo field problem.

We did recently switch over to "Sophos" virus protection and the beginning of this week sat down with network administrator and made sure that our tables were being excluded from scanning, thinking that there might be some kind of issue there. I was assured that they all are now (originally were not all, but some of them). I am not able to determine any user who can be linked to the problem.

Make SURE all tables, indexes, AND MEMO FILES are REALLY excluded from scanning.

Make sure all workstations that connect to the data have good, tested, reliable UPSs. Make sure any routers/switches/hubs do too! Fox tables are vulnerable anywhere along the data chain from the workstation across the network to the server. Interruptions anywhere along the line will break them (one of the HUGE reasons to go client/server).
