连接超时??????
最近公司做一 MIS 系统(后台为SQL Server 2000),以前是用 BDE 做数据访问部件,因考虑到 BDE 已经停止更新,在新版程序中换成了 ADO , 在同样的程序,同样的服务器,同样的数据访问量的情况下,程序几乎每天要报几次 "<em>连接</em><em>超时</em>" 错误,而在 BDE 下就没有问题. 后来, 我到服务器上, 把 SQL Server 的内存选项改小了些,同时把服务器上的一些设置进行了优化. rn 这样, 情况稍好了些,一天只会出现一次"<em>连接</em><em>超时</em>" , 本人有些不解,到服务器上进行观察,发现服务器上一切正常.rn 但有一个细节就是, 如果程序正常时, Win 2k 客户端是的网络批示器的灯是在一直在闪,如果要是出现 "<em>连接</em><em>超时</em>" 错的话网络指示灯就会闪一个然后就没有反应.rn 麻烦各位给分析一下, 以前有没有碰到类似问题,如何解决的. 或有什么设置要求这类的.rn 这里的是 100M 网络,全部通过交换机<em>连接</em>(二到三层分枝), 30 台机器, 联想万全P4 服务器.rn

VNC连接超时
一:bug截图 二:原因分析 远程<em>连接</em> 远程<em>连接</em>是要提供地址的,这里的地址是IP+桌面号,比如:192.168.1.23:2。随后提示你输入密码,此密码就是刚才第1个步骤这是的密码。 一般情况下,如果按照正确的安装方法,在服务器中安装了VNCserver后,就可以在客户端<em>连接</em>了。但是,如果服务器端打开了防火墙,可能会阻止<em>连接</em>过程。 三:解决
