Hi Joe,
Since this is an operational station (and considering you already spent a
considerable amount of time on this) have you considered reinstalling the
software/OS on the machine (or restoring a backup)? Worst case it will tell
you if this is a hardware issue or software issue. I believe based on the
hard drive replacement, firmware upgrade on the RAID and things working in
the background (share, RDP) that the problem is clearly on the Windows side
of things (see below the few other options on the hardware side).
Reinstalling (or restoring a backup) may be the less time consuming task
for you at this point (if it works, it will not tell you what was wrong,
but if it never happens again, really, you should not care that much).
If reinstalling is not an option, I would try the following:
- Update video card driver (or reinstall the existing one)
- Generate a system diagnostic report using: perfmon /report
- Run a Windows Memory Diagnostic: mdsched.exe (requires reboot)
- May sound strange, but I saw similar things happening caused by a bad
monitor, not the computer. Worth checking the monitor, cable and any
extenders you may have in between.
- Does it lock with different users? My guess is that it locks with the
same user, since you have to have that user logged to run the plant, but
can you leave a different user for a test? this will also tell if this
issue is related to the user profile or not.

I confirmed today that while the machine appears frozen to the operator, I
can connect to shared folders from the AW and copy and paste files. It also
appears that RDP can connect, as far as I can tell. So that means the whole
computer is not dead, just that user session. I wonder if there's a way to
force a logoff from the domain controller, rather than hard shutdown,
although that still doesn't fix the problem of it freezing in the first
place. Could this mean the problem is software/memory and not hardware?
