Computer Name Issue: Domain Joined
- 
 This is a computer joined to the domain (laptop) 
  The computer name shows as Device-LT00684, however in AD for what ever reason, the canonical name is much different DOMAIN/Computers/-Device-LT00684 CNF:443877f9-ab72-4657-b397-ee7b99098aa8Running host name on the device itself again shows that the device name is just LT00684. What would cause such weirdness?

 @gjacobse Weird is right. the closest I've seen is when 'nix boxes get a DHCP - they send this number that is some form of extended MAC as the hardware ID. Interested to hear what you find out.

 https://community.spiceworks.com/topic/2288212-strange-extra-long-linux-mac-address-in-dhcp-active-leasesNot clicking the link, but it is the last 4 sets of the MAC address and the machine id as noted in /etc/machine-id. It is part of the DHCP RFC.
