When transferring a project from one PC to another, a SqlException occurred, I checked the project on the first PC and everything works again, but nothing works on the second one. On both costs SqlExpress 2012.
Additional information: Connection timed out. Timeout expired on the stage after the entrance. It is possible that the connection timed out while the server was performing the login process and sending a response, or it happened while trying to create several active connections. The time spent trying to connect to this server was: [Pre-Login] initialization = 634; handshake = 1827; [Login] initialization = 0; authentication = 46; [Post-Login] complete = 13069;
Connection string:
<connectionStrings> <add name="userStore" connectionString="Data Source=.\SQLEXPRESS;Integrated security=SSPI;AttachDBFilename=|DataDirectory|\DataBase\UserStore.mdf;User Instance=True" /> </connectionStrings>
