COMMAND

    DNS

SYSTEMS AFFECTED

    Win NT 4.0 (server)

PROBLEM

    The Domain Name  System (DNS) fails  with an access  violation and
    ceases to resolve names.

    If  a  DNS  query  is  modified  so  that  the  original   query's
    AnswerCount field is greater than  0, the DNS server may  cause an
    access violation (AV).

    If the AnswerCount  is greater than  0, we expect  to already have
    data from the original  query, but in this  case, the data is  not
    present.

SOLUTION

    Obtain the following fix or  wait for the next Windows  NT service
    pack.   This  hotfix  has  been  posted  to the following Internet
