说到Novell,总得提一下微软和它的网络操作系统之争。微软的NT Server发展较晚,在96年以前的时间里没有多大影响,然而到了97年底的时候,NT Server在市场上已经占了优势。微软当然明白,NT的成功不在技术,而在于 …… ( 这是商业秘密)。NT采用图形界面,更易于被用户接受,但从技术角度来说,NT作为一个网络系统有太多的不足。微软雄心勃勃,准备在xx(未知)年推出新 的NT Server,并引入了目录服务-active directory。但大家认为它的目录服务不会比NetWare目录服务(NDS)更好,况且NDS已经存在了4年并经受了考验。
Novell公司在1998年推出了NetWare 的新版本NetWare 5,它的核心支持纯正IP协议,全面支持Java,并在易用性上有了长足进步,显然,Novell对自己的技术信心十足。与新版本同时推出的还有几个应用 软件,这是Novell的一大进步,与NT相比,基于NetWare的服务器软件要少得多,Novell也认为NetWare是最好的网络平台,而NT是 个理想的应用平台。
