一、启用远程管理
1、将管理服务器的trusthost列表改为*
运行Set-item wsman:localhost\client\trustedhosts –value *
2、在远程服务器上运行Enable-PSremoting
注：
在本地服务器上以Administrator运行“Enable-Psremoting 、 Winrm Quickconfig 、 Set-WSManQuickConfig”，均提示“访问被拒绝”，可能的原因如下：
1.在工作组计算机上，确认组策略： secpol.msc > Local Policies > Security Options > Network Access: Sharing and security model for local accounts - change to classic
2.修改注册表：Set-ItemProperty –Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System –Name LocalAccountTokenFilterPolicy –Value 1 –Type DWord
3.确认WinRM服务是否正在运行，Windows Firewall服务是否正在运行，网络位置是否不是“公用”，如果要启用PS远程管理，此时网络位置不能被设置为public，因为Windows 防火墙例外不能在网络位置是public时被启用。
4.Telnet localhost 47001是否可以连通
5.运行 winrm get winrm/config 是否会提示“访问被拒绝”
6.Administrator密码不能为空
远程启用开启之后可以在cmd命令窗口输入wbemtest测试是否可以连接远程服务器，如图：
连接成功的状态如下所示：
下面就可以来取每个服务器的磁盘空间了
