Well we have this Asp.Net application that we installed at a customer but now some times we get a SqlException that says "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." now the wired thing is that the exception comes instantly when i press the button, this does not happen every time i press the button so its random.. any idea what i could try to pinpoint the problem?

We are using the EnterpriseLibrary Database block if that matters...
