  2. In the navigation bar, choose the same Amazon Web Services Region as the existing directory.

  3. On the EC2 Dashboard, in the Launch instance section, choose Launch instance.

  4. On the Launch an instance page, under the Name and Tags section, enter the name you would like to use for your Windows EC2 instance.

  5. (Optional) Choose Add additional tags to add one or more tag key-value pairs to organize, track, or control access for this EC2 instance.

  7. In the Instance type section, choose the instance type you would like to use from Instance type dropdown list.

    1. To create a new key pair, choose Create new key pair.

    2. Enter a name for the key pair and select an option for the Key pair type and Private key file format.

  9. On the Launch an instance page, under Network settings section, choose Edit. Choose the VPC that your directory was created in from the VPC - required dropdown list.

  10. Choose one of the public subnets in your VPC from the Subnet dropdown list. The subnet you choose must have all external traffic routed to an internet gateway. If this is not the case, you won't be able to connect to the instance remotely.

    For more information on how to connect to a internet gateway, see Connect to the internet using an internet gateway in the Amazon VPC User Guide.

  11. Under Auto-assign public IP, choose Enable.

    Note

    After choosing the Domain join directory, you may see:

    An error message when selecting your Domain join directory. There is an error with your existing SSM document.

    This error occurs if the EC2 launch wizard identifies an existing SSM document with unexpected properties. You can do one of the following:

    • If you previously edited the SSM document and the properties are expected, choose close and proceed to launch the EC2 instance with no changes.

    • Select the delete the existing SSM document here link to delete the SSM document. This will allow for the creation of an SSM document with the correct properties. The SSM document will automatically be created when you launch the EC2 instance.

AmazonSSMManagedInstanceCore provides the minimum permissions necessary to use the Amazon Systems Manager service. For more information about creating a role with these permissions, and for information about other permissions and policies you can assign to your IAM role, see Create an IAM instance profile for Systems Manager in the Amazon Systems Manager User Guide.

    5. On the Name, review, and create page, enter a Role name. You will need this role name to attach to the EC2 instance.

    6. (Optional) You can provide a description of the IAM instance profile in the Description field.

    7. Choose Create role.
