Hi Mark
I have exactly the same problem and know for fact that it’s not the FOG service.
I finaly fix it by putting the password for account in registry under HKLM\software\microsoft\windows NT\current version\winlogon
I setup the key called DfaultUserPassword.
there is a program called windowsautologin.exe that does all that for you.
I also noticed that the password will be removed from registry after the number of autologon is over.
I appreciate if you tell mw what solution you found.
thanks
