missing ctrl+alt+del logon prompt

[soonerkid]

Windows NT 4.0 workstation has no ctrl+alt+del logon prompt. Default wall paper intact. Have successful reboot with no errors noted. I simply have no logon prompt. This problem is constant and TechNet has nothing to offer for this topic. Has anyone seen this before? Thanks in advance for any assistance.

Try pressing SPACE when the "Press SPACE BAR NOW to load last known good..." message comes up, then press "L" to load it.

That should roll back your PC to the configuration that was saved when you last successfully logged in. MCSE NT4/W2K

Thanks for the suggestion but the problem still exists. One thing I didn't mention in my original post ...I even have an active mouse pointer. The system does not hang.

Any further comments or suggestions will be very appreciated.

Hey dude...I have the same kind of problem here in Visa. My NT workstations appears sometimes with the Ctrl+Alt+Del logon screen missing, and there´s nof file I can replace that can fix it. Is the same condictions you said: Mouse working,keyboard working, but no ctrl+alt+del screen. The solution I found so far was re-install the image using Norton Ghost and start from 0.
I hope someone find a "light" for us...

Usually, when Alt-Ctrl-Delete is not present, it means that lsass.exe is corrupt. This is the file that's responsible for the log-on screen. When it dies, you have problem either logging on or off.

In order to get around it, you need to boot up with the NT installation CD (or 3 installation diskettes if your CD drive is not bootable. You can create 3 installation diskettes by running winnt32 /ox from command line using the NT4 installation CD).

Then simply boot up using either the CD or diskette, and choose the repair option to restore the lsass.exe.

This should let you boot back up. However, you would notice that the NT installation is probably back to either no SP or SP1, depending on the patch level of the installation media.

This means that just about every other services and applications would stop running. I am going to try to repatch the installation with SP6a. Though I don't know whether that's going to fix the problem. However, it at least gets you to log back on.

Hope this helps.
