We have found RDP can stop working, as other items, because the profile on the Network card changes from Private to Public.
How do you change this back from public to private without a reboot?
We have a simple solution below.
NOTE: This has been tested and working however we always recommend you take full backups and be cautious of any system changes as every environment is unique.
Powershell. Here is an example of changing the network profile of a network interface called Ethernet1 from whatever it is now to “Private.” I got this info from Get-Help Set-NetConnectionProfile -Full.
PS C:\>$Profile = Get-NetConnectionProfile -InterfaceAlias Ethernet1
PS C:\>$Profile.NetworkCategory = "Private"
PS C:\>Set-NetConnectionProfile -InputObject $Profile
