ランダムなSQL接続の問題。作品は、その後、動作しないし、次に、BAM作品！もう一度動作しませんか？

Question

ここでWebMatrixを使用していて、DBを持っていて、そこにない接続文字列がランダムに私にエラーを投げつけるまでは正常に動作していました。これはいつも時々起こります。WebMatrixのバグだと思っています。私が作った変更には関係ないので、どこかの設定を忘れるか失ってしまいます。

ここでエラーがスタックトレースとともに、です：（このような長いエラーについて謝罪）

なぜ私にこれをやり続けるWebMatrixのでしょうか？誰かが私がこれを解決するのを手伝ってくださいできますか？私は無限に捜し求めており、幾分関連したページをたくさん見つけましたが、それを稼働させることはできませんでした。

はあなたに

確認をお願いし、TCP煙突は、WebサーバーとSQL Serverの両方で無効になっていることを確認してください。 http://technet.microsoft.com/en-us/library/gg162682(WS.10).aspx
