Hi, I am using samba to serve a myob premier file to a number of win98 machines. The file is around 140mb and access is generally very slow. oplocks are turned off. when accessing it from a win2000 machine, it is a bit quicker and the logs (log level = 3) seem quite different (SMBreadX instead of SMBlseek). Is this likely to be the cause of the performace differences, and where can i find documentation on the differences. Thanks Joe
