Gina customization

[Guest]

Hi All,

Is it possible to customize the gina.dll so as to remove the Welcome screen
at the system boot time? I am working on a device which has a LAN network,
where Files/Folders are required to be shared among devices over a cluster of
network.
I first tried using Minlogon, later I came to know that we can’t create
shares using Minlogon easily, as in case of Windows Logon (I will have to use
Net.exe or WNetUseConnection etc).
If I use windows logon shell then I have to hide (remove) the Welcome screen
as well as the password messages at boot time. I know that there is a third
party solution available from Front motion and Logon studio to customize the
user logon, but is it possible to do modification in logon gina.dll to
achieve a Custom Shell with Windows Logon? (Is there any link?)
I tried the following with Windows Logon to remove system messages at
start-up.
1) Set DisableStatusMessages to 1
2) Set Logon type to 0
3) Set AutoAdminLogon to 1

With these settings I am able to hide the system messages at boot time but
for a very small fraction of seconds I can see some of the system messages
(probably username password messages) on the screen.
Any help will be greatly appreciated.

Regards
Roshan

Yes, it is possible. There are products that either replace the splash
screen or the GINA. Here are some links:

Hello Sean,

Thanks a lot for the information, great help...
In my yesterdays post I have mentioned that with the following settings:
1) Set DisableStatusMessages to 1
2) Set Logon type to 0
3) Set AutoAdminLogon to 1
I am able to hide the windows status messages at windows Logon, though I
could see the Admin password screen for a very fraction of time. Later I have
added the following in the registry:
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Integer 'DisableCAD', 1.
Now with this setting I even don’t see the user logon screen (which appears
for a fraction of second), but I don’t know whether this will have any side
effect?
Can you guide me on this?
Thanks once again for the help.

Regards
Roshan.

I have seen this setup before and it should be no problems. If you ahve
multiple users, then you may have to re-consider.

Yes, we will be having a single user system but the device will be on network
with other devices connected together(we should be able to share files
folders of other devices on the network)
