在我工作的环境中，有时用户的Active Directory（AD）主驱动器在登录时未映射，因为它们未连接到网络。之后，当他们通过VPN连接到网络时，他们需要能够映射他们的AD家庭驱动器。我在PowerShell中创建了一个脚本来执行此操作但是，在Windows 10上，我收到错误“对象引用未设置为对象的实例”。并且脚本无法映射用户的主驱动器。如果我在Windows 7上运行相同的脚本，它可以正常工作。对此问题的任何帮助将不胜感激。

.SYNOPSIS
Script to map a users home folder
.DESCRIPTION
The script will check to see if the user running it is found within Active directory. If the user does exist it will get the AD properties for the user.
Once the AD properties are known it will check to see if the home folder and path exist and are mapped.
If they are already mapped it will open explorer.exe to that location.
If they are not mapped, it will map the folder and open explorer.exe to that location.
.PARAMETER CRQ
Takes the CRQ number as input. Should be a string or integer.
.PARAMETER Name
Takes a string as input, this should not contain any spaces or special characters. Will be part of the log file name.
.EXAMPLE
C:\PS> .\MapHomeDrive.ps1
This will map the users Active Directory Home drive letter to their home share
.INPUTS
None
.OUTPUTS
None
