The installation is a Windows 2008 R2 server with an Exchange 2010. I am trying to install BESX on it, for which a user account is needed to login on the domain controller and run the installer. I keep getting:
The User Profile Service failed the logon. User profile cannot be loaded.
Everytime I try to login, even after I add the "BESAdmin" account to either Administrators, Domain Controllers or both. I've even changed the Allow Local Login policy to even specifically include the account.
Another poster who had a similar problem with the same error message stated that this happens with new accounts (like in my case) or accounts that have no v2 profiles (?) yet. He self-answered that one should copy c:\users\default from another installation. I do not have that option, so I am really hoping for some other solution.
Had the same problem. See http://social.technet.microsoft.com/Forums/windowsserver/en-US/95c8635c-76fa-47ff-a03c-a44d1e9a599b/server-2008r2-the-user-profile-service-failed-the-logon-user-profile-cannot-be-loaded?forum=winservergen. The solution listed on Microsoft Technet was to check that all privileges on files and folders in c:\users\default were correct. In my case I learned from the eventvwr that one obscure Visual Studio file had no privilege for read to Domain Users.
After some random surfing on the Net, an advice I followed was to run msconfig, disable UAC and reboot. I logged into the machine! Why this works, I do not know.
