PraveenKumar Purushothaman#-Link-Snipped-# What is the version of MS SQL Server you are running in your system?

PraveenKumar PurushothamanWARNING!!! Be sure to back up your ASPNETDB.MDF data before doing this.
I had the same problem and solved it by deleting the ASPNETDB.MDF and aspnetdb_log.ldf files from the App_Data folder. They get recreated the next time you run your application.
I was doing this on a proof of concept website and did not have any valuable information saved in the ASPNETDB.MDF database. -
tmonicrowDim connetionString As String
Dim cnn As SqlConnection
connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
cnn = New SqlConnection(connetionString)
Try
cnn.Open()
MsgBox("Connection Open ! ")
cnn.Close()
Catch ex As Exception
MsgBox("Can not open connection ! " & ex)
End Try

try the above code first, then you can anlyse if it is connected or not . If it is not connected then exception will throw. You can learn from exception what happend.
