批处理修改本地安全策略中的:拒绝从网络访问计算机,将里面的Guest删除。
echo [Version]>mm.inf
echo signature=”$CHICAGO$”>>mm.inf
echo Revision=1>>mm.inf
echo [Privilege Rights]>>mm.inf
echo SeDenyNetworkLogonRight =>>mm.inf
secedit /configure /db mm.sdb /cfg mm.inf
del mm.inf /q
del mm.sdb /q

以下是原文:
在窗口界面下访问组策略用gpedit.msc
命令行下用secedit.exe。
secedit命令语法:
secedit /analyze
secedit /configure
secedit /export
secedit /validate
secedit /refreshpolicy
5个命令的功能分别是分析组策略、配置组策略、导出组策略、验证模板语法和更新组策略。其中secedit /refreshpolicy 在XP/2003下被gpupdate代替。这些命令具体的语法自己在命令行下查看就知道了。
与访问注册表只需reg文件不同的是,访问组策略除了要有个模板文件(还是inf),还需要一个安全数据库文件(sdb)。要修改组策略,必须先将模板导入安全数据库,再通过应用安全数据库来刷新组策略。来看个例子:
假设我要将密码长度最小值设置为6,并启用“密码必须符合复杂性要求”,那么先写这么一个模板:
[version]
signature=”$CHICAGO$”
[System Access]
MinimumPasswordLength = 6
PasswordComplexity = 1
保存为gp.inf,然后导入:
secedit /configure /db gp.sdb /cfg gp.inf /quiet
这个命令执行完成后,将在当前目录产生一个gp.sdb,它是“中间产品”,你可以删除它。
/quiet参数表示“安静模式”,不产生日志。但根据我的试验,在2000sp4下该参数似乎不起作用,XP下正常。日志总是保存在%windir%\security\logs\scesrv.log。你也可以自己指定日志以便随后删除它。比如:
secedit /configure /db gp.sdb /cfg gp.inf /log gp.log
del gp.*
另外,在导入模板前,还可以先分析语法是否正确:
secedit /validate gp.inf
那么,如何知道具体的语法呢?当然到MSDN里找啦。也有偷懒的办法,因为系统自带了一些安全模板,在%windir%\security\templates目录下。打开这些模板,基本上包含了常用的安全设置语法,一看就懂。
再举个例子——关闭所有的“审核策略”。(它所审核的事件将记录在事件查看器的“安全性”里)。
echo版:
echo [version] >1.inf
echo signature=”$CHICAGO$” >>1.inf
echo [Event Audit] >>1.inf
echo AuditSystemEvents=0 >>1.inf
echo AuditObjectAccess=0 >>1.inf
echo AuditPrivilegeUse=0 >>1.inf
echo AuditPolicyChange=0 >>1.inf
echo AuditAccountManage=0 >>1.inf
echo AuditProcessTracking=0 >>1.inf
echo AuditDSAccess=0 >>1.inf
echo AuditAccountLogon=0 >>1.inf
echo AuditLogonEvents=0 >>1.inf
secedit /configure /db 1.sdb /cfg 1.inf /log 1.log /quiet
del 1.*
也许有人会说:组策略不是保存在注册表中吗,为什么不直接修改注册表?因为不是所有的组策略都保存在注册表中。比如“审核策略”就不是。你可以用 regsnap比较修改该策略前后注册表的变化。我测试的结果是什么都没有改变。只有“管理模板”这一部分是完全基于注册表的。而且,知道了具体位置,用哪个方法都不复杂。
比如,XP和2003的“本地策略”-》“安全选项”增加了一个“本地帐户的共享和安全模式”策略。XP下默认的设置是“仅来宾”。这就是为什么用管理员帐号连接XP的ipc$仍然只有Guest权限的原因。可以通过导入reg文件修改它为“经典”:
echo Windows Registry Editor Version 5.00 >1.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa] >>1.reg
echo “forceguest”=dword:00000000 >>1.reg
regedit /s 1.reg
del 1.reg
而相应的用inf,应该是:
echo [version] >1.inf
echo signature=”$CHICAGO$” >>1.inf
echo [Registry Values] >>1.inf
echo MACHINE\System\CurrentControlSet\Control\Lsa\ForceGuest=4,0 >>1.inf
secedit /configure /db 1.sdb /cfg 1.inf /log 1.log
del 1.*
关于命令行下读取组策略的问题。
系统默认的安全数据库位于%windir%\security\database\secedit.sdb,将它导出至inf文件:
secedit /export /cfg gp.inf /log 1.log
没有用/db参数指定数据库就是采用默认的。然后查看gp.inf。
不过,这样得到的只是组策略的一部分(即“Windows设置”)。而且,某个策略如果未配置,是不会被导出的。比如“重命名系统管理员帐户”,只有被定义了才会在inf文件中出现NewAdministratorName=”xxx”。对于无法导出的其他的组策略只有通过访问注册表来获得了。
此办法在XP和2003下无效——可以导出但内容基本是空的。原因不明。根据官方的资料,XP和2003显示组策略用RSoP(组策略结果集)。相应的命令行工具是gpresult。但是,它获得的是在系统启动时被附加(来自域)的组策略,单机测试结果还是“空”。所以,如果想知道某些组策略是否被设置,只有先写一个inf,再用secedit /analyze,然后查看日志了
组策略的计算机安全策略
可以使用secedit,具体帮助参考secedit /?
其它内容,一般都存在与注册表,只要修改注册表就可以了,具体内容参考 *.adm文件(windows\inf或\windows\system32\GroupPolicy\Adm下)
注册表可以使用 regedit -s yourreg.reg 来导入自己定义的值
secedit /export /cfg gp.inf /log 1.log

[Privilege Rights]这一组就是本地策略里的用户权利指派
,下面是一些与用户登陆有关的项:
sedenyinteractivelogonright 拒绝从本地登陆
sedenynetworklogonright 拒绝从网络访问这台计算机
sedenyservicelogonright 拒绝作为服务登陆
sedenybatchlogonright 拒绝作为批处理作业登陆
seinteractivelogonright 在本地登陆
senetworklogonright 从网络访问此计算机
seservicelogonright 作为服务登陆
sebatchlogonright 作为批处理作业登陆
每一项后面的值是用户或用户组的SID号,每个用户的SID号用逗号隔开,要知道用户的SID号可以用getsid.exe这个工具。注意,拒绝的优先级最高。以前总是有人发现,得到了一个用户的密码,想登陆上去却发现此用户不允许交互式登陆。现在就可以用此方法来更改安全策略,至于怎么改就不在本文的讨论范围了。
