两个CNAMElogging的parsing方式不同（Windows 2003 Server）

注意：这是在进一步调查之后对先前问题的后续。

这个问题（到目前为止） 似乎被孤立到一个Win2003的DNS服务器（虽然我还没有尝试其他服务器types）

问题也是（截至2010年2月24日）作为MSDN论坛post在这里打开，但我希望有人可能能够帮助testing其他服务器types。

我遇到一个相当奇怪的DNS问题（Server = Win2003）

• DNS区域文件SPFconfiguration，支持从多个服务器和Gmail发送邮件
• 转发域名为flavours.me但保留own_domain.com/blog
• 将我的服务器上的MXlogging更改为Google MX？
• 我将如何/能够获得一个相当全面的域名列表？
• configuration绑定以提供DNS查询的默认IP

我已经开始直接与我的ISP进行调查了，我们遇到了一个奇怪的问题，如下所示。

注意：这些结果偶尔会以某种方式工作（testing最好在清除Win2003 DNScaching后执行）

首先，如果我们查看wilmot.me.uk的域名服务器logging，我们得到：

>>> nslookup -q=cname mail.wilmot.me.uk Non-authoritative answer: wilmot.me.uk nameserver = primary-dns.co.uk wilmot.me.uk nameserver = secondary-dns.co.uk 

现在有两个特别感兴趣的logging。

 >>> nslookup -q=cname mail.wilmot.me.uk Non-authoritative answer: mail.wilmot.me.uk canonical name = wilmot.me.uk.mail.aaisp.net.uk >>> nslookup -q=cname mail2.wilmot.me.uk Non-authoritative answer: mail2.wilmot.me.uk canonical name = C.mail.aaisp.net.uk 

现在问题SEEMS是本地Windows 2003 DNS服务器不正确跟随CNAME数据。

使用以下命令：

 >>> nslookup -d2 -q=a mail.wilmot.me.uk. >>> nslookup -d2 -q=a mail2.wilmot.me.uk. 

我们可以看到：
mail.wilmot.me.uk返回一个NXDOMAIN结果然而：
mail.wilmot.me.uk用IP地址返回一个NOERROR结果（如预期的那样）。

它会APPEAR，CNAMEs没有被正确地遵循。

奇怪的是，以下两个回报如预期。

 >>> nslookup -q=a wilmot.me.uk.mail.aaisp.net.uk. >>> nslookup -q=a C.mail.aaisp.net.uk. 

如果有人能够帮助解决这个问题（甚至通过确认“是的，它会导致在xxx操作系统的问题”或“似乎在yyy操作系统中工作正常”，这将是伟大的。

下面的日志数据显示，Win2003甚至不会解决wilmot.me.uk.mail.aaisp.net.uk. CNAME在第一个实例
