Die Web-Anwendung nutzt die Membership-Funktionalität von .NET 4 und funktioniert aus VS2010 heraus problemlos. Anschließend wird die Website in ein Verzeichnis veröffentlicht und von diesem Verzeichnis auf den WebServer (IIS) kopiert. Beim
Test funktionieren die Seiten solange, bis die Express-Datenbank benutzt werden soll: Da bekomme ich dann einen Fehler, den ich nicht weiter deuten kann:
Server Error in '/' Application.

Frage 1: Funktioniert die ExpressDatenbank mit IIS 6 auf Windows Server 2003 nicht?
Frage 2: Wenn 1 positiv: Wie kann ich den Fehler einkreisen?
