In Denver, a Y2K Project Management Plan had been in place since September 1996. Culminating literally years of preparation, the NBC Denver Command Center was activated at 4:00 p.m., Friday, December 31, 1999. Its purpose was to monitor the conditions and status of Denver's mission-essential facility along with its mission-essential systems. After midnight, and already assured that system backup capabilities executed properly, functional groups used quality assurance checklists to verify correct operation of the mainframe, other mid-range systems, systems software, communications network, LAN/PC systems, and the building facility.

Applications testing started at 5:00 a.m. Saturday morning after prime data center components were tested and deemed operational for Y2K and beyond. FPPS and FFS applications were tested by NBC and client staffs, and found to work normally. At 4:00 p.m. Saturday afternoon, the Command Center was deactivated.

In Washington, D.C., the NBC Technology Services Division (TSD) in the Main Interior Building completed the remediation for all Office of the Secretary (OS) employees in the MIB, including the NBC. The TSD Y2K Remediation Team evaluated and applied operating system patches to a Hewlett Packard minicomputer and 565 end user workstations. Only 86 workstations were completely replaced. In addition, a total of 1,076 non-compliant end user software applications were either replaced or upgraded. Nine non-compliant servers were identified and replaced, and essentially all 53 telecommunications hubs were replaced. Most legacy applications were modified to accommodate a 4-digit year, but one application had to be completely rewritten due to the reliance on non-compliant commercial off-the-shelf software. Additional telecommunications remediation efforts included replacing one telephone system, one videoconferencing system, several FAX machines, VCRs, and a teleprompting system.

On Friday, December 31st and Saturday, January 1st, a Y2K Command Center and Readiness Team was on-site to perform minicomputer, application, and network system checks and testing, and to perform testing on more than 50 end user workstations throughout the MIB. The telecommunications team ensured that all MIB telephone systems and OS Wide Area Network communications were operational. No Y2K-related problems were encountered.

At all NBC locations, the following Monday, January 3rd, was deemed to be the true test to determine if any customer-reported Y2K problems would occur. NBC Help Desks carefully monitored trouble calls received and none were deemed to be Y2K-related.
