Hello everybody ! I have a timeout expired error from an application written in Delphi and MDAC 2.6 . This is OK on my development machine. But on the customer side i have this particular and horrible message. I already run the profiler and didn't give advice for indexes. I already rebuilt the database with script and i still have the same problem. This error occurs randomly with any of the queries. I already put the command and time out to 0 and nothing better. Do you think i have to reinstall SQL server 2000 ?
