Error 1609
error applying security Settings. The user is not a valid user or group. This could be due to a problem with the package or a problem connecting to a domain controller on the network.
Simply put, the ASPNET user does not exist or the domain in which the user resides has a problem. If the user doesn’t exist, create a user named ASPNET, or if it does, it could be a domain problem.
