数日前に Web サイトを公開しましたが、接続文字列に問題があるようです。同じ結果で何度か変更しようとしましたが、これに多くの時間を費やしました。
私の実際の接続文字列は次のとおりです。
<add name="Server" connectionString="user id=xxxx;pwd=xxxx;Data Source=emboole.mssql.somee.com;Initial Catalog=emboole" providerName="System.Data.SqlClient" />
私のプロバイダーからのいくつかのデータ:
MS SQL Server address: emboole.mssql.somee.com
Login name: xxxx
Login password: xxxx
Connection string: workstation id=emboole.mssql.somee.com;packet size=4096;user id=xxxx;pwd=xxxx;data source=emboole.mssql.somee.com;persist security info=False;initial catalog=emboole
スタックトレースでは、次のことがわかります。
[Win32Exception (0x80004005): The system cannot find the file specified]

みんなありがとう！
編集:接続文字列の問題ではなく、サーバー構成の問題だと思い始めています。
