At least now it's consistent!
Is /etc/passwd readable by everybody?
Is the system mount for / (or /etc) the same as your user mount?
Is /etc/passwd on a local disk?
One way or another, SYSTEM cannot read /etc/passwd,
although (going back to your original mail), it was initially
able to read it.

That's OK, you are logged in as U-TANT-A01\winwa02
