Hi, i have a host site at your server and link is http://www.wisematrix.com Before it was working well. Now every 1 or 2 days its giving me the error http 503 service unavailable. Server people telling its the problem because you are not closing the connection problem. I have checked each and every code at my end, connection is closing properly. At most of places I am using DataAdapter which is connection less object. How to resolve this. Thanks Reena Jain
