Hi Guys.....

>It's not a good idea to use Windows 95 as a server for a database application. If you must do this I would recommend at least using your server only as a server and not running anything else on it (especially something that eats resources the way VFP does).

I agree 100%. I have seen a tremendous amount of problems with VFP on Win95 peer-to-peer including almost daily corruption of tables. Moving to NT will help a lot. He will *never* get complete reliability for a VFP app in Win95 PPN.

>>Our app is a 9mb EXE. The network consists of 5 Win95 machines, peer-to-peer file and printer sharing. The system that acts as file & print server is a P200MMX with 32MB. (By the way, on boot up I get the message that memory is 31MB + 1MB shared memory)
>>Our application runs on every system, including the one that acts as file server.

>>Most of the user actions involve reading data from the server via SELECT into a local cursor. New data is entered in local tables and validated before being written to the database on the server.

You are probably table buffering, right? You almost have to entirely forego buffering on Win95 peer-to-peer. This has been my experience.

>>2. the network behaves strangely: print jobs 'hang', copying files to/from the server is aborted with the message 'network resource failure'. Even when all our apps are closed, the network still crashes for simple file copy actions. Re-booting the file server seems to fix this.
