I got it working by remoting into the host and disabling Windows firewall. Then refreshing LMI window and opening a new cmd prompt.

Might need to log out and back into logmein for cmd prompt to work after disabling Windows Firewall.

 

Steps done:

Remoted into computer.

Disabled Window Firewall for Domain, Private, Public.

Set computer network to private.

Logged out of LMI and back in.

Opened cmd prompt.

    It works for a little bit, then the next version breaks it, then they fix it again.

     

    We did set a GPO to disable the firewall (still set to Domain), since our AV has its own anyways, and we haven't had problems with this latest version. We had it disabled for over a year though and it didn't help with the last version, so it's hit or miss.

    All nice and easy except that doing so on some Windows servers will then lock the machine out of everything except local keyboard access. Might be fine on workstations but be careful as this is also exposes the machine to all manner of network nasties.
