Re: Problem with Invalid System Time dialog preventing autologon.

Thanks steves,

The problem is that this is a system which we sell to customers, using of the shelf hardware (AmPro CoreModule 600). So I'd rather fix this in software instead of modifying every single board we deliver.

I was also unable to disable this message on a XP Proffesional installation. It seems this question has gone unanswered in multiple posts around the net. Is there nobody who knows how to disable this message box or knows from which dll/service it originates from?

Thanks in advance,
Øivind

I would think that the system bios would write a valid time into the
CMOS clock during POST. Perhaps your motherboard manufacturer could
provide a modified BIOS that would initialize the clock correctly (Set
it to a version number or something). I have in the past reverse
engineered my BIOS to accomplish such things. There are a couple of
books out there that contain the I/O maps for the CMOS Ram maps that
alllow you to figure out what needs to be done.

If you compared the time/date seen in the computer's CMOS ram utility
with the range of allowed times for a windows clock, maybe you could
see why this is occurring.

Hi all,

I've got a problem with a modal dialog preventing our systems autologin.
The dialog contains the following text:

Title:
Invalid System Time

Text:
The time or date on your system is invalid. Please use the date/time
applet in the Control Panel to properly set your system time and

I believe the dialog appears because we do not have a battery in our
hardware and the real time clock is reset every time power is lost.

I've found a preliminary fix to this problem by enabling implementing
message box interception, but this solution presents some problems since
all message boxes automatically automatically returns the default button
as result.
I used the following registry settings:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Error Message
Instrument]
"EnableLogging"=dword:00000001
"LogSeverity"=dword:00000000
"EnableDefaultReply"=dword:00000001
"TypesSupported"=dword:00000007
"EventMessageFile"="%SystemRoot%\\System32\\User32.dll"

I also tried setting the NoPopUpsOnBoot and ErrorMode keys like this:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows]
"ErrorMode"=dword:00000002
"NoPopUpsOnBoot"=dword:00000001

but they did not seem to have any effect. Is this messagebox a special
case which is not affected by the NoPopUpsOnBoot setting?

If anybody have any suggestions how to remove this dialog it would be
greatly appreciated!
