Windows 7 Beta中的DNS域名bug

Win7之家（ www.win7china.com）：Windows 7 Beta中的DNS域名bug

 Windows 7Beta和Windows Server 2008 R2 Beta的发布也有了一段时间了,最近几天，越来越多的bug被大家找了出来，下面这个bug就是Windows 7 Beta在处理DNS时的一个问题，测试者发现当用户通过Windows 7 Beta或Windows Server 2008 R2 Beta加入15个字节以上主机名的DNS主机时，系统会返回错误信息“The attempt to join this computer to the << domain_name >>.com domain failed. The parameter is incorrect.”（无法加入到XXXXXXXXXXXXXXXX.com，参数错误）

而微软也确认了这一Bug并强调此Bug只有在遇到15位以上主机名时才会出现，而15位及15以下都不会有任何问题。这里的15位指的是.com这个“.”之前的字节数。比如Northwindtraders.com，这样的域名就会返回错误信息，而像bbs.ithome.com这样的就不会。

目前，微软提供了一个有关此问题的紧急补丁  ，不过并未明确表示何时发布更新以永久解决此问题。

附部分原文：

Following the availability of Windows 7 client Beta and Windows Server 2008 R2 Beta, Microsoft revealed that neither of the next versions of its Windows operating systems were able to join domains with names exceeding 15 characters in length. Any attempt to join Windows 7 client Beta or Windows Server 2008 R2 Beta machines to a Domain Name System (DNS) with a 15+ character domain name would result in an error message, the company informed - “The attempt to join this computer to the << domain_name >>.com domain failed. The parameter is incorrect.”

Microsoft revealed that this scenario would take place if “[users] try to join a Windows 7-based or a Windows Server 2008 R2-based computer to an existing domain by using the System Properties user interface, the Netdom.exe command, an unattended setup, the Djoin.exe command, or another mechanism. [And if users] try to use the Active Directory Installation Wizard (Dcpromo.exe) to install Active Directory Domain Services on a member server.”
