This code runs for a small file of 15 records but not for 600. I have no idea what timeout happened. I checked the ODBC and SQL. I changed the IIS server timeout from 120 to 360 but no change. The timeout actually happens at about 45 seconds. The table has about 130 records in it when it fails (starts with zero).
