無法打開登錄請求的數據庫<database>。登錄失敗。登錄失敗的用戶<user>

當我用management studio訪問數據庫時，一切正常，我訪問表......但是當我運行用相同用戶訪問數據庫的Windows服務時，會引發此錯誤。無法打開登錄請求的數據庫<database>。登錄失敗。登錄失敗的用戶<user>

您是否檢查過您是否在Windows服務中傳遞了與您登錄管理工作室時相同的確切密碼？ – 2013-03-22 18:41:07

是的，我使用app.config的副本/粘貼進行登錄。 – 2013-03-22 18:45:18

可能將不得不分享你用來連接的代碼。還評論一下，如果這個SQL身份驗證或Windows身份驗證？並且是錯誤中提到的數據庫，您嘗試連接到的數據庫。還要確保你連接到正確的服務器等等。 – 2013-03-22 18:52:10

嘗試確保用戶有權訪問連接字符串中的初始目錄。如果連接字符串沒有初始目錄，請添加一個用戶有權訪問的目錄。這可以解釋爲什麼它在一種情況下工作，而不是另一種情況。

當前配置：'Data Source = s-vtgn02 \ prdsbvt04; Initial Catalog = sttcoletorsbvt; User ID = usr_stt_coletor; Password = 'usr_stt_coletor' ：db_datareader和db_datawriter。 – 2013-03-22 18:58:37
