I need to logon to multiple computers on a domain exactly like the program logon.exe or RC Logon which uses logon.exe ( http://sourceforge.net/projects/rclogon/ ), but uses strong passwords ie @#%$.  I don't know if a program exists our there other than logon.exe.  I searched @ softreech and logon is not opensource and they are not willing to show the code so that it can except all ascii characters.

Anybody know if they used sendkeys, or edit GINA (which I don't think they did) to do this?  Or of a program that excepts strong passwords?

The only solution I know of (besides Gina) is the use of SendInput. However the application must be a service and run in the Winsta0\winlogon desktop. So my guess is that they create a service on the fly, get into the winlogon desktop and send the username and passwort to the logon window.
I also guess that special chars are treated differently in the SYSTEM process (which the service lives in) because the service has a different keyboard profile. But It's just a guess.

But maybe AutoLogon from SysInternal may help you

I think there was even the source code available. Today a deep search should reveal it.

I don't think autologon will work.  I am on a domain, in a computer lab where each user has shared rights to various servers.

I need to remotely logon a whole classroom or the whole lab for changes to an image and so forth.  RC Logon uses logon.exe so that you can just send a specified username + password to the multiple pc's without storing any logon information.

Having the same issue as well. Seems like psexec is not able to pass through characters when the shift key is being press so lets say if i am typing $ which we get by pressing Shift and the number 4, it will just show 4 on the remote pc. Using rclogon as well but trying to figure out how to pass those characters over to the remote client.
