                     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.

   If there are any questions, please contact Major Boyd at
   Comm (703) 692-7580 or DSN 222-7580, e-mail to [email protected].
