Explanation:
Configure managed accounts
You need to register managed accounts with the farm to make the accounts available to multiple services. You can register a managed account by using the Register Managed Account page in Central Administration. There are no options on the Register Managed Account page to create an account in Active Directory Domain Services, or on the local computer. The options can be used to register an existing account on the SharePoint Foundation 2010 farm. Perform the steps in the following procedure to use Central Administration to configure managed account settings.
To configure managed account settings by using Central Administration
1. Verify that the user account that is performing this procedure is a farm administrator.
2. On the Central Administration Web site, select Security.
3. Under General Security, click Configure managed accounts.
4. On the Managed Accounts page, click Register Managed Account.
5. In the Account Registration section of the Register Managed Account page, enter the service account credentials.
6. In the Automatic Password Change section, select the Enable automatic password change check box to allow SharePoint Foundation 2010 to manage the password for the selected account. Next, enter a numeric value that indicates the number of days prior to password expiration that the automatic password change process will be initiated.
7. In the Automatic Password Change section, select the Start notifying by e-mail check box, and then enter a numeric value that indicates the number of days prior to the initiation of the automatic password change process that an e-mail notification will be sent. You can then configure a weekly or monthly e-mail notification schedule.
8. Click OK.
