# Renaming your Amazon Managed Microsoft AD directory's site name
<a name="ms_ad_rename_site"></a>

You can rename your Amazon Managed Microsoft AD directory's default site name so that it matches with your existing Microsoft Active Directory (AD) site names. This makes it faster for Amazon Managed Microsoft AD to find and authenticate your existing AD users in your on-premises directory. The result is a better experience when users login to Amazon resources such as [Amazon EC2](http://www.amazonaws.cn/ec2/) and [Amazon RDS for SQL Server](http://www.amazonaws.cn/rds/sqlserver/) instances that you have joined to your Amazon Managed Microsoft AD directory.

To do that, you must be logged in with the **Admin** account or with an account that is a member of the **Amazon Delegated Sites and Services Administrators** group. For more information about this group, see [What gets created with your Amazon Managed Microsoft AD](ms_ad_getting_started_what_gets_created.md).

For additional benefits on renaming your site in relation to trusts, see [Domain Locator Across a Forest Trust](https://techcommunity.microsoft.com/t5/ask-the-directory-services-team/domain-locator-across-a-forest-trust/ba-p/395689) on Microsoft's website.
