Ctrl-Alt-Del to unlock Computer > Login > Black Sreen
I have 10 new Win7(64)Pro Dell Optiplex980
8 of 10 are having this issue
Network w/ SBS2k3 Domain Policy requires (for pci compliance) to force all workstations to lock if inactive for 10 minutes.
When a user returns to their pc, the press Ctrl-Alt-Delete to provide their login creds. Upon doing so correctly, the screen goes black, and appears to be completely unresponsive... The only option is the hard boot the device...
In some cases if we elect to lock manually (rather that wait 10 min) login from this seems to work most of the time, but in some cases I end up with the same result described above...
One other note, is that I have yet to experience any of the other issues I've read through on this forum (thank god) meaning, I have not loggon problems on any of my machines unless unlocking a pc that has a user already logged in... FYI, if I switch users, I've had a 100% success loggin in doing this, It only seems to affect a user that is unlocking the machine that is currently logged in...
All 10 were configured out of the box with Dell setup, all fully updated, all configured the same way... We've disabled all identifyable power management settings (win/bios), disabled hibernation (powercfg -h off). In short all 10 machines are identical... The weird part is that 2 of the machines have never had a problem with any of this...
It seems like once locked, the machines don't want to unlock. ps: on rare instances the pc did unlock but it took 3-10 minutes, in most cases indefinitely (meaning we gave up and had to get to work, so we had to hard boot)
This is a real mystery... That's why I'm calling in Scooby and the gang!
