What To Do
A incremental backup was created during the presence of SGN. After that SGN was uninstalled from the system.
When you restore the incremental backup, after the uninstallation of SGN, afterwards the reboot will end up in an emergency shutdown of the system.
This shutdown was initiated by SGN and is a security feature. This is the result if no PoA (Power-on-authentication) was performed neither manual authentication
nor autologon mode.
Boot the system in safe mode and change the following registry key for Windows XP:
1) HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
2) change the "GinaDll" entry to "msgina.dll"
3) reboot the system.
Boot the system in safe mode and disable the following SGN service in Windows Vista:
1) disable the service "SGNAuthService"
2) reboot the system
