SQLSERVER（2000）修改密碼時(shí)提示 “錯(cuò)誤 2812: 未能找到存儲過程 'sp_password'?！?解決方法

[重要通告]如您遇疑難雜癥,本站支持知識付費(fèi)業(yè)務(wù),掃右邊二維碼加博主微信,可節(jié)省您寶貴時(shí)間哦!

昨天給一個(gè)青島的客戶做管家婆的演示，開啟了遠(yuǎn)程1433端口，早上在登陸管家婆就發(fā)現(xiàn)無法登陸，提示sa密碼錯(cuò)誤；我也沒操作啥，為啥錯(cuò)誤呢？看了一下系統(tǒng)日志，霍霍好多登陸信息，我一個(gè)虛擬機(jī)在內(nèi)網(wǎng)做了演示，你能干啥哦；還這么瘋狂的掃描；

現(xiàn)在有很多自動(dòng)掃描1433端口的軟件，會破壞sp_password存儲過程。造成在修改SA密碼的時(shí)候出現(xiàn)2812錯(cuò)誤，那如何解決呢，我們現(xiàn)在來說說；

用WINDOWS身份驗(yàn)證登陸到SQL SERVER的查詢工具。復(fù)制--粘貼--執(zhí)行下面的代碼即可；全程圖解，具體請看下圖；
