我使用下面给定的过程从SQL Server发送SMS。它工作得很好，直到昨天晚上。通过SQL Server 2008中的sp_OAMethod发送SMS中的问题
但是，今天我收到以下错误： -
-2146697212 Msg 50000, Level 16, State 1, Procedure pr_SendSmsSQL, Line 61
sp_OAMethod Send FAILED!
我补充说：“sp_OAGetErrorInfo会”知道确切的错误，那么就说明我给出的消息如下： -
Error Source Description
msxml3.dll Unable to connect to the target server.
请指导如何解决这个问题。相同的代码在另一个SQL Server上正常运行。
存储过程的代码： -
SET ANSI_NULLS ON
SET QUOTED_IDENTIFIER ON
GO
