Adding a user in AD

I have inherited a Windows 2000 AD network and I’m trying to add some users to the server. Everything works fine up until it asks for a password. No matter what I put in W2K says that the password doesn’t meet the requirements of the security policy. Granted I have looked at all of the different password policies on the server and half are either not defined or I have met the requirements for them. I think I did change the admin password a long time ago when I was doing consultant work and had to go with something similiar to 7a7d7M7I7N. Any help on this matter would be much appreciated. Thanks.
