I have just installed a new PC running Windows 7 Professional for an existing user on our Windows 2003 domain. When she tries to change her domain password, she gets an "access denied" error message. I am able to change her password on the server, and the new password works fine. I have added her to the local administrator group. But no success. As a test, I added a 2nd user from the same domain to the users on the PC. The 2nd user is able to login and successfully change her password. Not sure where to go from here except to create a new account on the Domain for the 1st user. Any help would be appreciated. This is a single forest, Windows 2003 domain, with no other trusts. This is the 1st Wiondows 7 PC added to the domain. All other workstations are Windows XP.

Check her account in AD, is it set to require logon to change password in the "Users must log on in order to change password" check box in the Account Policy ?

Thank you cschaar. That took care of the problem.
