国庆前，参加了HP的培训，在考试中心也过了HP APP的考试。

培训难度还可以，顺便知道了一些HP的资料，有些用过，有些没用过，有空要研究下~

hard bounce
A hard bounce is an e-mail message that has been returned to the sender because the recipient's address is invalid. A hard bounce might occur because the domain name doesn't exist or because the recipient is unknown.

目前杀毒软件一直用Nod32，但是相对于很多大公司的产品，针对企业和权限管理还有很多欠缺的地方，今天碰巧看到Eset的企业版，有提到这个东西，贴一下

ESET Remote Administrator v2.0.110 has been released. This release contains the following changes:

• fixed updater for NOD32 v2.x
• minor bugfixes

今天看到报告说，Windows Server 2008的传输速度比2003快45倍，针对于网络共享的传输。

 这也许能解决目前File Server的面临的问题，看测试报告确实相对于SMB1有质的提高，但对于实际运行的文件服务器，文件数量庞大，文件容量较小，能否起到作用，暂时还未得知。

 期待它能给我们带来惊喜~

以前一直以来没有关注过CNAME，也不觉的缺少它有什么问题，今天无意看了它的一些介绍。。

其实之前我都是直接用A记录来完成这些设定，每当修改时，确实要修改很多。

 别名记录(CNAME)

也被称为规范名字。这种记录允许您将多个名字映射到同一台计算机。 通常用于同时提供WWW和MAIL服务的计算机。例如，有一台计算机名为“host.mydomain.com”（A记录）。 它同时提供WWW和MAIL服务，为了便于用户访问服务。可以为该计算机设置两个别名（CNAME）：WWW和MAIL。 这两个别名的全称就是“www.mydomain.com”和“mail.mydomain.com”。实际上他们都指向“host.mydomain.com”。 同样的方法可以用于当您拥有多个域名需要指向同一服务器IP，此时您就可以将一个域名做A记录指向服务器IP然后将其他的域名做别名到之前做A记录的域名上，那么当您的服务器IP地址变更时您就可以不必麻烦的一个一个域名更改指向了 只需要更改做A记录的那个域名其他做别名的那些域名的指向也将自动更改到新的IP地址上了。

当然，区别并不是只有这么一点：有网友这么说“当一个域名添加了CNAME记录，则该域名将继承CNAME记录值所设定域名的除NS记录以外的全部记录。”
