Skype Room System V2 device will not auto login to Skype for Business

So I ran into this too.  So I thought I would share my process for adding a machine to the domain.

1. The names should follow the standard server naming.  <removed>
2. The computer account must be first pre-created in the domain.  If this is not done, the system will get GPOs assigned to it, which will cause major issues, so make sure to PRE-CREATE the computer account at : OU Path
   1. Right click on the OU and choose new computer
   2. enter the computer name, all lower case
   3. For user or group choose Domain Admins, or another user account to add it the system.  I would recommend using your regular user account <for why, the reason has been removed, but you can use any account or group>
3. Go to the Skype Room System
   1. on the lower right corner click the gear icon
   2. click settings, the password for Administrator is <removed>
   3. Click on Windows Settings and then Admin Sign in
   4. Click on Administrator in the lower left corner and use the same password
   5. From there change the computer name
      1. Click on the Folder Explorer
      2. Expand This PC
      3. Pres and hold on This PC to bring up the context menu
      4. Choose Properties
      5. Under Computer name click Change settings on the right
      6. In the Computer Name Tab, click Change to rename the computer
      7. Enter the computer name, and click Apply/OK and reboot the system
   6. Go back to the administrator desktop like you did above
      1. This time, when you click Change, set the Member of Domain to <removed> (Make sure the computer name has already been created in the correct OU)
4. Remote desktop to the system the username is .\admin and the same password
   1. Because adding the computer to the domain removes the auto logon, it has to be added manually.  A GPO will not add it correctly. Run the following from an elevated command prompt:

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v AutoAdminLogon /t REG_SZ /d 1 /f

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefualtUserName /t REG_SZ /d Skype /f

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v DefualtPassword /t REG_SZ /d "" /f
