OS 9 network permissions

Hello,

We have two windows domains with users accounts mirrored in each domain. The domains are trusted to each other. One an NT domain and one a w2k domain. Our file server (w2k server) was in the NT domain and the membership was switch to the w2k domain. We have a program call ExtremeZ-IP running on this server to share folders out the mac clients. Each mac user has a user folder on the file server with the same permissions for their w2k user and NT user account. I recently removed the NT account from the security tab of each user folder and the mac clients could not access their user folder. It is seen through the mac with a lock on it. One way I was able to get into the user's folder was when connecting to the user share using the chooser I type <w2k domain>\<username> in the username field and then their password. This allowed me to access the share using the w2k user account instead of the NT account. The problem is that I can't find a way to tell the mac os 9 os to use the w2k account \ domian controller instead on the NT 4 account / domain controller. If anyone has any suggestions it would be greatly appreciated if you would share them.

Thanks
Rob
