远程桌面排错
最近遇到了一个比较棘手的问题,用户远程桌面无法连接,我的博文中之前也写到了一篇远程桌面排错,但是这次的和之前的大不相同
= = 原因排查步骤
1)首先当然是查看报错,这个是我自己机器上截图的,报错信息都一样
2)首先查看服务器是否开启了远程访问
3)查看目标是否可以ping通
4)查看服务是否正常启动
5)如果要正常远程到目标必须可以telnet到目标的远程端口,默认为3389,这个端口不通,我们之前已经将防火墙关闭了
6)本机上telnet 127.0.0.1 3389,这么做的话可以排除外界因素的干扰,当然还是不通
7)然后我在本机使用netstat -ano 命令查看监听的端口是否有3389,并没有找到3389端口,5800和5900端口是VNC服务器的端口,也是一款远程软件,还好有它不然都没法排错

8)端口都找不到,是不是有人修改了默认的3389端口,在注册表如下路径
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber查看值是否为3389,我这里并没有修改,但是我考虑可能是端口被占用?
9)我就修改端口试试看吧,修改端口的话需要修改两个值,修改完之后重启RDS服务即可
基数调整为十进制然后填入3390
重新启动服务后就会生效
= = 考虑第三方因素
1)之前同事处理过一个问题,就是因为其他服务占用了3389端口后,修改端口就可以访问了,但是我处理的这台服务器有一个不同点就是他本地都监听不到端口
2)修改端口后依旧是之前的问题,之后听客户说他们有一块心跳网卡,之前远程还是正常的,可能是心跳网卡有关系,将心跳网卡禁用后,我重启了服务器,好像和它没什么关系
3)考虑第三方服务造成了服务故障?cmd中输入msconfig,这个操作需要重启,我还关闭了杀毒软件
4)可能是RDS组件无法使用3389端口?,我就下载了一些RDS组件的更新,系统是08R2企业版,前三个正常安装,后面的不适用,没有什么影响,安装完成后重启
升级RDS相关的组件:

5)今天接着找问题,找到问题之后继续更新...
