The Micros server, which controls the cash registers in the CBORD One-card system, ran out of disk space on the C: drive, causing serveral services to crash. This in turn caused the cash registers to go offline.
The pagefile was split among the C: and D: drives in the folowing manner: 500 MB on C: and 1 GB on D:, and serveral temp files and an old log file were deleted.
The NT backup was moved from 3:30 AM to 2:30 AM, because it was not finishing before opening time for the cafe and diner.
