w2k remote connection problem to win98

can anyone help me find solutions to my problem? I have a w2k pro pc that i want to connect to a win98 pc via dialup connection. My problem here is no user and password cannot be authenticated during the connection. It always prompts the error 691: access was denied because the username and/ or password was invalid on the domain. To clarify further my settings, i have just simply enabled the allow caller access on the win98 pc and it has no domain settings on it or complicated network settings what so ever even in my w2k pro pc.

Is there any configuration that ive missed here? Can any one help me find solutions to this? Any help would be appreciated…
