Hi All,
I have developed an application in Asp.Net 3.5. In this, I have used 4-tier architecture.
Server Detail
-------------
Application hosted on Windows Server 2008 64bit OS with IIS 7. Server is having 32GB of RAM, and 200GB of hard drive.
Both publish Application and database hosted on same server.
Problem
-------
I have one Review form where in I am trying to submit the review of Employee.
When single user logging in to the application on web server, application is working fine. User is able to submit their reviews. But as soon as it increases to more than one, it creates problem. Let's say, suppose more than one user is clicking on Submit button at a time to submit Review then only one employees record is storing on database rest all users data are not storing, but all Users are getting a message saying "Submitted Successfully".
Also I checked the error in Event Log, and I am getting a message like below.
