How to change password manually for a managed account?

Hello,

I have accounts in Active Directory that are used for SharePoint managed accounts, like search, user profiles synchronization, web application pool, and others. I like to change the passwords for these accounts. I have them changed in Active Directory, so then I go Central Admin to change the password in SharePoint. When I go to Central Admin, I do the following:

1.      Select Security
2.      Select Configure managed accounts
3.      Select Edit to edit an account
4.      Select Change password now
5.      Select Set account password to new value
6.      Type in a password
7.      Select OK

Is this correct to change the password manually?  When I do this, I get a

"The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements."

The password is more than 6 characters long, and contains numbers, upper and lower case letters and non-alpha characters, like ! and $.

I can change the password with this complex policy just fine in AD, but Windows 2008 R2 and SharePoint don’t like the password.

Can you help?
