Hi,
Is anything being reported in the event logs? Sounds like a hardware problem, maybe bad RAM in one of the machines.

Had similar problem recently, CPU fan had failed and cooked the CPU, it was injecting rubbish into the files just prior to locking up.

>I have one user who in addition to running a network with 14 machines maintains 3 remote users connecting using either RemoteAdministration or NetOP. Since we have moved to VFP9 this site is crashing at leaset once per month. The crashes write garbage neatly into several files. After cleaning the garbage out the files are still ok. If anyone is using a setup similiar to this I would appreciate any advice. Thanks.
