扩展储存过程被删除以后可以有很简单的办法恢复：
删除

drop procedure sp_addextendedproc
drop procedure sp_oacreate
exec sp_dropextendedproc 'xp_cmdshell'

恢复

dbcc addextendedproc ("sp_oacreate","odsole70.dll")
dbcc addextendedproc ("xp_cmdshell","xplog70.dll")

这样可以直接恢复，不用去管sp_addextendedproc是不是存在
-----------------------------
删除扩展存储过过程xp_cmdshell的语句:

exec sp_dropextendedproc 'xp_cmdshell'[/cdoe]
恢复cmdshell的sql语句
[code]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

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

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_cmdshel
