                      REGISTRATION OF TAC USERS
     
    On 25 October 91, the Defense Information Systems Agency
    (DISA) published DDN Management Bulletin 85, which discussed a
    problem with the timeliness of TAC users being re-registered
    with the Network Information Center (NIC).  This problem
    surfaced as a result of MILNET hosts being deconfigured and
    moved behind concentrators/gateways.  In Management Bulletin
    85, the 15th of December had been set as the date the NIC was
    to terminate network access to all TAC users utilizing TAC
    cards registered to deconfigured hosts that had previously
    been direct-connected to the DDN.
     
    The purpose of this bulletin is to advise all concerned that
    the 15 December 91 termination date has been extended.  The
    reason for this decision is simple--there was not enough
    time to clear the logjam of users requiring re-registration
    processing both at the MILDEP level and at the NIC.  The
    process of re-registering TAC users who now fall behind
    concentrators/gateways had become a difficult and convoluted
    problem.  However, DISA and the Military Departments have had
    several meetings on this issue and have come to agreement on
    how to solve the problem long-term.  Therefore, once new
    registration procedures are implemented and re-registration
    is moving smoothly, a new termination date for TAC cards
    issued under the "old" deconfigured hosts will be set.
    This will probably occur within the next few months and will
    be done in conjunction with the annual re-registration 
    process.
