    after created a new user 'Oracle' and granted 'administrators' group to it on win2k, I installed oracle8.1.6 with tapical mode, and then, the above error appeared when the 'oracle database configuration assistant' is initializing database. Have you even experience such issue? Any advice will be appreciated.

    If you are using Advanced Security option or Kerberos, you should comment (place a # sign in front of the parameter) or remove the authentication request parameter:
    SQLNET.AUTHENTICATION_SERVICES= (XXX) in the sqlnet.ora file, located in the Oracle_Home/network/admin directory ...
    hope this helps
