Hi neil,

Thanks for you viewpoint. I'll certainly will keep your mail in case I need it in the future.
I'm not a system administrator, though I had to troubleshoot some problems with a FPW database many years ago in a LAN/WAN to prevent corruptions, so I digged through quite a number of mskb articles a learned all about chaching and oplocking. I agree I previously had problems with server caching, but actually never had any problems with oplocking. In fact this exclusive oplock provided use with an tremendous performance advantage when working over a WAN since the writes were cached on the clients and saved back to the table when it was closed withhout having to use tables exclusively.

I agree that most systems that are set up at clients (mostly government) probably have set their disk caching off. However I'm not that sure about oplocking.

Walter,
