远程通过网页控制服务器进程
借用目前国内外最流行的远程控制软件平台，比如网络人远程控制软件，无需做端口映射即可穿透任何内网，对局域网内的任意电脑进行远程控制、屏幕监控、视频监控、文件管理、系统进程观察等等操作;是远程服务器高效管理的必备工具。点此下载免费使用。

有服务器上操作系统的账号、密码以及该服务器的ip地址。如果是管理员组的账号，可以考虑用telnet登陆该服务器，条件是该服务器开telnet服务。在cmd下，用命令操作。

如何在局域网中实现屏幕监控
如何在局域网中实现屏幕监控？很多企业都有这个需求，就使用超级眼屏幕监控监控软件，来实现这一功能。除此之外，这款监控软件还可以键盘输入记录，网址访问记录，流量记录，文件操作记录，聊天记录监控等。如何轻松实现局域网电脑屏幕监控？下面我们来了解！
下面是局域网屏幕监控，给大家演示局域网电脑屏幕监控的方法：
1.我们在百度搜索输入局域网屏幕监控找到超级眼电脑屏幕监控软件，选择下载到电脑上，监控软件分为管理端和被控端。我们先安装管理端到管理者电脑上，无需设置一键安装就可以了。
2.将被控端，解压到员工电脑上，并且安装。一键安装，无其它设置，安装完成后，重启电脑即可，自动开机隐蔽运行。
3.在管理端上，输入软件商提供的账号密码登录，可自行修改密码。在管理端界面上，点击“扫描”，在左侧可以看到在线或者离线的被控端。
4.管理端上，选择在线被控电脑，在功能界面进行操作，单个员工监控时，点击“屏幕监控”，多个员工监控，点击“多屏幕监控”，这样就可以看到员工电脑的电脑屏幕实时画面，也就是电脑屏幕监控。
5.怎么卸载软件，被控端是隐蔽运行的，被控电脑无权限卸载，需要在管理端电脑上，选择对应的被控端，右键进行卸载。管理端，直接在管理者电脑上自行卸载就可以了。
