NT_STATUS_WRONG_PASSWORD

From the Windows File Service Log:

  User "obrien" failed to authenticate with "dsAuthMethodStandard:dsAuthSMBNTKey" (-14481) :(
[2007/07/25 17:18:30, 1] auth_ods.c:opendirectory_smb_pwd_check_ntlmv1(427)
  opendirectory_smb_pwd_check_ntlmv1: [-14481]opendirectory_auth_user

  check_ntlm_password:  Authentication for user [Joseph O'Brien] -> [Joseph O'Brien] FAILED with error NT_STATUS_WRONG_PASSWORD

This repeats multiple times.

The server is OS X 10.3.9. It is joined to an NT domain. At some point, I must have used my NT credentials for something on this machine because it apparantly keeps trying to use it. The problem is, the Windows Server eventually locks my account due to all the bad login attempts.

The only place I could find my user name was on the LDAP setup screen. I used those credentials to authenticate to the Windows LDAP server. However, I have since changed that to another user. I have also checked the keychain.

How can best go about correcting this situation?

Thanks.
