win7 访问 共享目录 的延迟问题

[Liangming2003]

一台装有WES7的PC访问局域网内的一个共享目录，从开机在“运行”窗口键入地址\\15.15.182.122, 到弹出用户名密码窗口需要90秒时间，关掉窗口再次打开仍需要45秒左右，而局域网内另一台装有WES7的PC访问相同共享目录，可立即弹出窗口，请教可能是什么原因造成的？


以下是用Network Monitor 截下的网络活动，列出有延迟的那台机器的比另一台多做的网络活动，为什么访问相同的目录，其网络行为却不一致？比如第一行这个SUN Remote Procedure Call(111)，求高手指教。

启动慢的原因，是NFS服务导致的性能问题。 关闭NFS服务： 运行services.msc ，将“client for NFS”的服务停止，启动类型改为手动即可。
