Sometimes, there are background processes and application that need the user to be logged on to the PC before they will run. On a domain PC, this is normally not possible. However, you can modify the registry to enable this. NOTE: the password will be clearly seen.
In regedit, navigate to HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Add or modify the key, AutoAdminLogon (String) to 0
Enter in the user credentials in the three keys – DefaultDomainName, DefaultUserName, DefaultPassword.
