After the first time or two that the files are accessed, they will be in the system cache of the server. Make sure that all oplocks are set on, and fake oplocks are also on (perhaps both are by default??). This will help the clients. Remember too, that the access will only be as fast as the network connection - maybe you need 100BaseT, or maybe their own segment for these really demanding clients... look into a switch. -- Edward Schernau http://www.schernau.com Network Architect mailto:ed@schernau.com Rational Computing Providence, RI, USA
