My cntrl-alt-delete saga

Post by GusCalderon »

Hello folks. This is my first post and only my second week working for a public library, so please forgive my ignorance, but I need to see if someone may hold some answers for me. :)

We are securing several terminals for public internet use, and I'm using PWB v2 and HideGUI with some success. However, the cntrl-alt-delete has continued being a problem. On some computers, I'm able to disable the task manager using gpedit, but an annoying little popup (you cant' do this, your administrator has blocked it (paraphrasing)) keeps popping up in the taskbar every time someone tries it. The result is a taskbar filled with these messages. I can't truly hide the taskbar because the timer program we use minimizes to the task bar so it dissapears if you do (there's no fix to this yet, I'm working on disabling the minimize).

Now, my predesesor used an old program called 'surfmate st' to supress any open windows, so the task manager need not be surpressed, since it will automatically close as soon as it's open. This is a great program, with a fundamental flaw: it's old, they don't make it any more, and I don't have any documentation so I have no idea about the care and feeding of it. Any information about this program would be greatly appreciated. But does anyone have any idea how to supress that little pop up? Or do you have a different approach to this problem?

Ok, my next problem is with newer computers that are "domain" based. What I mean by that is that when you press cntrl-alt-delete, the windows security popup comes on, with buttons that say "lock computer", "task manager", "logoff", etc. When you disable the task manager from the gpedit, it just removes some of those buttons, but the windows still pops up every time you press the dreaded combination. Any idea how to deal with these?

Any help would be greatly appreciated.

You should allow the Ctrl-Alt-Del (Windows Security dialog) to display, and use either a Group Policy or edit the Registry directly to disable the buttons on the security dialog.

There is also a PWB add-on called PWBCloseWindow that will close windows as they activate by name that may be useful.

If you would like to delete all of your data, you must uninstall the program on the server computer. You then should delete the c:bpa directory this does not get removed when you uninstall. From there, you may install the software from the CD. The client installations do not hold any data at all. To get rid of them, delete the c:bpa directory there is no option to uninstall.

I would make sure there is no uninstall either in Add/Remove programs under the control panel or in the BPA directory.

If not all you can do is delete. Be aware I did this myself with the Demo. I was looking for BPA in the Add/Remove programs, and missed that it was under Demo BPA. So I deleted. Unfortunately, it left all sorts of stuff in the registry and would not allow me to reinstall the full version.

Anyway, I did find the demo uninstall ran it..it gave all sorts of errors, but it did uninstall the entries preventing the re-install.

In the end, uninstall is best. The fact yours is "disabled" what ever that means, may mean that it was uninstalled and all that is left is the BPA files that do not get deleted automatically.
