Forum Control Panel Log in

I think I've posted this in the correct forum now, and thanks for previous help.

I'm running this forum on a closed Intranet site and we are having problems with logging into the "Forum Control Panel". We use NT Logon which I'd guess is what is causing the problem with a password conflict when trying to access the forum control panel. As this is an Intranet forum we don't need the high security of the extra admin log on for Forum Administration, Is it possible to switch off the extra level and allow admins full control of the forum including forum management without the need for the extra log in. I am using moderators for posting control and all members are classified as staff (Posting and replies) or Guests (Viewing only). With no Ladder promotion. I think I may be waffling by now, Hope I've explained it right and

Thanks in advance for your help
