Thank you so much. I have been able to find a way arrount this issue. Thee problem was that, i am deploying the application i created on my pc to another system, but i was getting the default sql server instance wrong on my connection string. Instead of
"Data Source= ItSupport\SQLEXPRESS;initial catalog=POSTRANS;integrated security=true", i was entering the above string.

Thanks for the help.
