Thanks for the reply

in web.config I have

      <add key="ConnectionString" value="packet size=4096;integrated security=SSPI;data source=(local);persist security info=False;initial catalog=mydb" />  

which is my standard connectionstring I replaced it with

        <add key="ConnectionString" value="server=(local);database=mydb;integrated security=SSPI;" />

and it is working

Thanks

Mike
