Re: Windows XP Logon Error



Hi Mike.

I see you are still struggling with this. What I would try is to have the
user that is having the problem logon to a SP2 domain computer that he has
never logged onto before that other users can logon to. I know you reference
roaming profiles in a past post so I would also disable roaming profile for
the problem user temporarily so that he will only be using a new profile
that the operating system would create for him the first time he logs onto a
computer. If that does not help try adding the user to the local
administrators group on a domain computer temporarily to see if that helps
or not. Check the user's account properties/account - account options in
Active Directory Users and Computers to see if account options are the same
as users that do not have the problem. Beyond that I can not think of much
more and Google did not help as this seems to be an uncommon problem but
would suggest that you also post in the Active Directory newsgroup. Also
enable auditing of system events for success and failure, object access for
failure, process tracking for failure, and privilege use for failure on the
client computer in Local Security Policy to see if any helpful events are
recorded the next time the problem occurs. --- Steve

Hello,

We are having problems as we upgrade to Windows XP Service Pack 2 across
our
Enterprise. When certain users login, they receive a pop up message
stating
a message similar to the following, which is logged in the system event
log
under event ID 26: "Application popup: SAS window: winlogon.exe -
Application Error : The exception unknown software exception (0xc0000409)
occurred in the application at location 0x75979eca."

The pop up window forces the user to click OK or Cancel upon which the
machine reboots.

If the same user attempts to login to a machine with Windows XP SP 1 that
has not been upgraded, they can login fine.

The error occurs before the profile loading begins and before any user
settings are applied through group policy. Just to be sure, we reset the
user profile and disable group policy settings on this computer and for
this
user. The results are still the same.

If anyone has seen this error or can offer any advice it would be greatly
appreciated.
