                       DDN/MILNET TAC HERALD

The Defense Communications Agency (DCA) has been in the process of
developing a patch to all MILNET Terminal Access Controllers (TACs)
that would remove the DDN "WELCOME" banner.  This was being done as a
security measure to cease the identification of the system as
belonging to the DDN/MILNET, and the type of operating system/software
it uses, etc.  In addition, DCA wishes to make it clear that
unauthorized use of the DDN/MILNET is not permitted.

The purpose of this bulletin is to inform addressees that the new TAC
herald is ready for fielding.  An example of the new herald is as
follows:
               FOR OFFICIAL USE ONLY
               NIC 1-800-235-3155
               29 TAC 114 #:20

If you have any questions or problems concerning this change, contact
DCA, Code DODM, no later than 14 November 90.  Otherwise, the new TAC
herald will be changed effective 15 November 90.

DCA POC is Maj. Boyd, DSN 312-222-7580 or Comm 703-692-7580.
