เริ่มเข้านิดๆ แล้ว
คือ มี webserver 2 ยี่ห้อ ให้เครื่องเดียวกันโดยกำหนดไว้คนละ port
พอจะเขียน asp.net ให้ insert ลงฐานข้อมูลแล้วมันไม่ทำงาน
พอรันไปสักพัก database server เดี้ยง แบบนี้ใช่ไหม

database server เดี้ยงนี้คง service มันถึงฆาตอย่างว่าแหละ ให้ restart ดูว่าหายไหม
ส่วน insert ไม่ work ให้ลองใช้คำสั่ง query ง่ายๆ ดูว่าได้ไหม ถ้าได้แสดงว่า insert command ผิด
ไม่ใช่แก็ซโซฮอล์

ลองตรวจสอบดู connection string ดูอีกทีครับ หรือเอามา post ให้ช่วยกันดูก็ดีครับ
** ถ้า SQL Server ที่ใช้ เป็น Express edition ที่หลัง host ต้องใส่เป็น \SQLExpress ด้วยนะครับ
