When I try to change my password using Start > Windows Security > Change a password, I always get the error "Unable to update the password. The value provided for the new password does not meet the length, complexity, or history requirements of the domain." I get this error no matter how unique and/or complex the password is.
On the other hand, if the Domain Administrator uses Active Directory Users and Computers to set my account to "User must change password at next logon", I can then set it to a new password, including passwords rejected by the Windows Security/Change Password mechanism. Why?
Windows 7 in Active Directory Domain.
