I am connecting to SQL through OBDC from MSAccess. I have approx. 50 machines that will be using the SQL. There are currently about 15 machines on SQL. about 25% of them run very fast. the other 75% run very slow. All the odbc settings are the same, all the SQL drivers are the same. It seems to be computer oriented. The same machines run fast no matter what scenario. What network protocol should I be running and would this make a difference.
