navigator something similar that happens with networked PC’s is an orphaned network connection. This issue occurs when a remote network drive is disconnected or removed from service, but it’s still connected on the machine exhibiting slowness.
Right clicking the problematic drive in most cases won’t allow you to disconnect, but running this at the command prompt will work
This assumes that drive P is being used, so modify accordingly
net use p: /delete /yes
The orphaned network drive letter should now be removed.
