原因：存储过程被恶意篡改了，打开master数据库，点开扩展存储过程项，可以看到很多的存储过程路径已经被篡改，正常的都是.dll的路径，将不是该路径的存储过程先删除先执行，存储过程的路径可以参照其它机器好的sql数据库的存储过程
修复一下存储过程
先删除
drop procedure xp_cmdshell
drop procedure sp_OASetProperty
drop procedure sp_OAMethod
drop procedure sp_OACreate
drop procedure xp_regdeletekey
drop procedure xp_regwrite
drop procedure sp_password
drop procedure xp_dirtree
drop procedure sp_password
后执行
exec sp_addextendedproc xp_cmdshell,'xplog70.dll'?
exec sp_addextendedproc sp_OACreate,'odsole70.dll'?
exec sp_addextendedproc sp_OAMethod,'odsole70.dll'?
exec sp_addextendedproc xp_regdeletekey,'xpstar.dll'?
exec sp_addextendedproc xp_regwrite,'xpstar.dll'?
exec sp_addextendedproc xp_dirtree,'xpstar.dll'?
exec sp_addextendedproc sp_OAGetProperty,'odsole70.dll'
