Creating FBA user from the timer job

Hi,

I'm trying to create FBA users from the timer job,

The code to it:

MembershipCreateStatus createStatus;
MembershipUser user = Membership.CreateUser(strUserID, strPassword, strEmail, "Test Question", "Test Answer", true, out createStatus);
switch (createStatus)
 {
  case MembershipCreateStatus.Success:
        //SendMail
          break;
  case MembershipCreateStatus.DuplicateEmail://Log in to the error file
           break;

   }

But it throws the error:

Unable to connect to SQL Server database in the timer job

Regards,
