Hi during a trial testing i found a minor issue, dont know how to report a issue when its just a trial so it goes here.
If you have to add a 2nd server to a domino domain and place the id file on the desktop of a domain joined machine the domino installer cant see the id file , unless the file is placed in all users or default users desktop profile.
Enviroment Domino 8.5 fresh from trial
Windows 2003 X64 Sp2 with all updates
