How to disconnect a network drive using powershell
In powershell you could issue a set of commands like this to disconnect a drive, given only the UNC that you used to connect, and not knowing the drive letter that was mapped.
The tricky part is that you have to escape the \ character to use it in the WMI query.
$Drive = Get-WmiObject -Class Win32_mappedLogicalDisk -filter "ProviderName='\\\\192.168.1.108\\d'"
net use $Drive.Name /delete
I would like to suggest using PowerShell's own Remove-PSDrive. For example:
Remove-PSDrive Y
Do not include a colon or a backslash; just use the drive letter only.
