错误2812:未能找到存储过程'sp_password'

解决方案：现在有很多自动扫描1433端口的软件，会破坏sp_password存储过程。造成在修改SA密码的时候出现2812错误下边是解决代码，用WINDOWS身份验证登陆到SQL SERVER的查询工具。复制--粘贴--执行就OK拉。 create procedure sp_password
@old sysname = NULL, -- the old (current) password
@new sysname, -- the new password
@loginame sysname = NULL -- user to change password on
as
-- SETUP RUNTIME OPTIONS / DECLARE VARIABLES --
set nocount on
declare @self int
select @self = CASE WHEN @loginame is null THEN 1 ELSE 2 END

-- RESOLVE LOGIN NAME
if @loginame is null
select @loginame = suser_sname()

-- CHECK PERMISSIONS (SecurityAdmin per Richard Waymire) --
IF (not is_srvrolemember('securityadmin') = 1)
AND not @self = 1
begin
dbcc auditevent (107, @self, 0, @loginame, NULL, NULL, NULL)
raiserror(15210,-1,-1)
return (1)
end
ELSE
begin
dbcc auditevent (107, @self, 1, @loginame, NULL, NULL, NULL)
end

-- DISALLOW USER TRANSACTION --
set implicit_transactions off
IF (@@trancount > 0)
begin
raiserror(15002,-1,-1,'sp_password')
return (1)
end

-- RESOLVE LOGIN NAME (disallows nt names)
if not exists (select * from master.dbo.syslogins where
loginname = @loginame and isntname = 0)
begin
raiserror(15007,-1,-1,@loginame)
return (1)
end

-- IF non-SYSADMIN ATTEMPTING CHANGE TO SYSADMIN, REQUIRE PASSWORD (218078) --
if (@self <> 1 AND is_srvrolemember('sysadmin') = 0 AND exists
(SELECT * FROM master.dbo.syslogins WHERE loginname = @loginame and isntname = 0
AND sysadmin = 1) )
SELECT @self = 1

-- CHECK OLD PASSWORD IF NEEDED --
if (@self = 1 or @old is not null)
if not exists (select * from master.dbo.sysxlogins
where srvid IS NULL and
name = @loginame and
( (@old is null and password is null) or
(pwdcompare(@old, password, (CASE WHEN xstatus&2048 = 2048 THEN 1 ELSE 0 END)) = 1) ) )
begin
raiserror(15211,-1,-1)
return (1)
end

-- CHANGE THE PASSWORD --
update master.dbo.sysxlogins
set password = convert(varbinary(256), pwdencrypt(@new)), xdate2 = getdate(), xstatus = xstatus & (~2048)
where name = @loginame and srvid IS NULL

-- UPDATE PROTECTION TIMESTAMP FOR MASTER DB, TO INDICATE SYSLOGINS CHANGE --
exec('use master grant all to null')

-- FINALIZATION: RETURN SUCCESS/FAILURE --
if @@error <> 0
return (1)
raiserror(15478,-1,-1)
return (0) -- sp_password 以上代码在SQL 2000 SP4上测试通过。

先在企业管理器中

在查询分析器执行以下代码：
　　create procedure sp_password
@old sysname = NULL, -- the old (current) password
@new sysname, -- the new password
@loginame sysname = NULL -- user to change password on
as
-- SETUP RUNTIME OPTIONS / DECLARE VARIABLES --
set nocount on
declare @self int
select @self = CASE WHEN @loginame is null THEN 1 ELSE 2 END
-- RESOLVE LOGIN NAME
if @loginame is null
select @loginame = suser_sname()
-- CHECK PERMISSIONS (SecurityAdmin per Richard Waymire) --
IF (not is_srvrolemember('securityadmin') = 1)
AND not @self = 1
begin
dbcc auditevent (107, @self, 0, @loginame, NULL, NULL, NULL)
raiserror(15210,-1,-1)
return (1)
end
ELSE
begin
dbcc auditevent (107, @self, 1, @loginame, NULL, NULL, NULL)
end
-- DISALLOW USER TRANSACTION --
set implicit_transactions off
IF (@@trancount > 0)
begin
raiserror(15002,-1,-1,'sp_password')
return (1)
end
-- RESOLVE LOGIN NAME (disallows nt names)
if not exists (select * from master.dbo.syslogins where
loginname = @loginame and isntname = 0)
begin
raiserror(15007,-1,-1,@loginame)
return (1)
end
-- IF non-SYSADMIN ATTEMPTING CHANGE TO SYSADMIN, REQUIRE PASSWORD (218078) --
if (@self <> 1 AND is_srvrolemember('sysadmin') = 0 AND exists
(SELECT * FROM master.dbo.syslogins WHERE loginname = @loginame and isntname = 0
AND sysadmin = 1) )
SELECT @self = 1
-- CHECK OLD PASSWORD IF NEEDED --
if (@self = 1 or @old is not null)
if not exists (select * from master.dbo.sysxlogins
where srvid IS NULL and
name = @loginame and
( (@old is null and password is null) or
(pwdcompare(@old, password, (CASE WHEN xstatus&2048 = 2048 THEN 1 ELSE 0 END)) = 1) ) )
begin
raiserror(15211,-1,-1)
return (1)
end
-- CHANGE THE PASSWORD --
update master.dbo.sysxlogins
set password = convert(varbinary(256), pwdencrypt(@new)), xdate2 = getdate(), xstatus = xstatus & (~2048)

楼主应该把代码设置回复可见，不然看的人多，回复少。

如果出现截图所示报错，建议将数据做好备份然后进行以下操作：

错误 0:无法装载 DLL Microsoft提示您请误随意操作SQL数据库以免对起数据库造成不必要的麻烦或该 DLL .
打开查询分析器，执行以下语句： drop procedure sp_OACreate
drop procedure xp_dirtree
drop procedure xp_regwrite
exec sp_addextendedproc N' sp_OACreate', N'odsole70.dll'
exec sp_addextendedproc N' xp_dirtree', N' xpstar.dll'
exec sp_addextendedproc 'xp_regwrite', 'xpstar.dll' 可能会再次出现这样的错误：未能找到存储过程 master.dbo.xp_dirtree|错误2812 再次打开查询分析器，执行以下语句：
use master
EXEC sp_addextendedproc xp_dirtree ,@dllname ='xpstar.dll'

操作完成如果正常即可，如果还有问题建议卸载当前数据库重新安装。
