局域网PING主机显示BAD OPTION SPECIFIED,但可以上网,什么原因?

我装的系统是XP
局域网PING主机 显示
BAD OPTION SPECIFIED
但可以上网!
是什么原因!
---------------------------------------------------------------

出现这种情况原因是TTL>255
一般ping某个IP会出现如下信息:

C:>PING 127.0.0.1

Pinging 127.0.0.1 with 32 bytes of data:

Reply from 127.0.0.1 bytes=32 time<10ms TTL=225
Reply from 127.0.0.1 bytes=32 time<10ms TTL=225
Reply from 127.0.0.1 bytes=32 time<10ms TTL=225
Reply from 127.0.0.1 bytes=32 time<10ms TTL=225

Ping statistics for 127.0.0.1:
Packets: Sent = 4, Received = 4, Lost = 0 <0% loss>,
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

请注意TTL=225

PING出现Bad option specified这种情况一般有2种
1.安装了防火墙.请设置防火墙.
2.安装了注册表优化软件(例如超级兔子魔法设置软件,本人安装了这个软件把里面的TTL设置成了256后就会出现这种错误,设置成<=255就可以了)
