>>It's Win95/98 clients running on an NT network. John - Thanks for the Netbeui suggestion. I'll try that. Also, after playing around with config.fp and moving all tmp files to a local directory, things have sped up tremendously. I also set files=99 and buffers=20 in the config.sys of the worst offending machines (p100's with 16MB RAM, Win95). The problem seems to have disappeared, but it's so sporadic, I can't say for sure.

I left the client site - but I will ask them about this. I have no idea about the infrastructure of the network, but what you're suggesting sounds quite reasonable. Their network is brand new (thus the upgrade to networked version of our software), so I'm guessing that they are 100base-t, but that's about all I can say at this point. I'm not highly versed in network technologies, and since they are pretty new to networks themselves, I wouldn't be at all surprised if the collisions were a cause of the problem.

I only have about 10 machines using our system, but they have hundreds of others connected ot their network. Could a simple 10 machine networked system still cause collisions like you mention?
