Device Un isolation Issue

[Bosanac89]

We have some issues with endpoints that when they are put into isolation and then trying to remove them isolation it will fail or just be in a pending state. 

Trying the force unisolation script does not work on these devices as we get a error message "unisolation failed with exit code 2". 

Has anyone run into these issues? 

Another thing that I have noticed is when a device is put into isolation it enrolls that device again and shows the same device twice in device inventory.

Encountered this for the first time as well. The networking stack seems to be interrupted to a greater extent. Normally, with isolation, we would still get telemetry into defender and intune. Currently the affected system is having difficulty even with DHCP at times.

Side note, the search for the phrase quoted in the original post is what I searched, Bing came back with too many results to sort through that were not on target, Google returned this post only.
