不能ping有些域名？
新换了wifi环境，在我的Windows8cmd 视窗里ping好像有点问题，我能ping到www.hotmail.com ，但是ping不到www.msn.com，也ping不到www.microsoft.com。但是在浏览器里我可以访问以上3个网站。我自己的网站在其他的网路下运行正常，但在这行的网路里我自己的网站连不上我的email伺服器，它出现错误信息"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."。 我也ping不通我的emailpop.aaa**.com伺服器。请问我的网路设置那里可能出了问题？
Windows8cmd 视窗里的 “Request timed out" 错误讯息如下：

Some popular sites such as amazon.com, microsoft.com, slashdot.org, and other sites that have had DoS attacks in the past may disable ICMP on their servers or setup other network settings that prevent a ping request be received or responded to. Because of this when pinging these domain names or their associated IP addresses you'll receive a "Request timed out." or get a "100% packet loss."
This is normal behavior for these sites and there is nothing that can be done to get around it.
看看你的DNS配置的是不是有问题。
或者更改一下DNS服务器IP 只要能解析，就可以正常工作。不是所有的设备都会对ICMP进行应答！ rayj88 发表于 2014-06-14 11:24 static/image/common/back.gif

Absolutely get to it.
You can try nslookup to find whether the server can be resolve to ip address, to make sure the server is online or not.
