AWS Simple AD–change subnet

i was working on a AWS project and setting up a workspace (desktop on the cloud) and 1 of the pre-requisite is active directories. I am using AWS in Sydney region. I setup my active directories (Simple AD)and realized AWS workspace does not support Sydney region on availability zone b and c, only availability Zone A is supported. I get error message like below when i tried to register workspace using my simple AD directories on availability zone b and c,

“

Unsupported Subnet

The selected directory was created in a subnet that is not supported by the WorkSpaces service, and cannot be registered. Please try with a different directory or contact the AWS Support Team on the community forums and via AWS Premium Support.

“

Workaround:

I've logged a support call with AWS support but the answer i get back is not possible to change the directories subnet. The workaround is to create a new AD connector. Make sure the AD connector is on the correct subnet (availability zone A)

make sure

- connected directory DNS is the same as simple AD

- NETBIOS name is the same as simple AD

- username and password – which is the user with domain admins rights in simple AD

- DNS must matched. you can get DNS by going into workspace – directories and expand the directories,

Once the AD connector is configured, you can now register the workspace with the new AD connector and start workspace.

 

It is an additional monthly charges but since my workspace also required MFA, which only support AD connector, hence this is ok for me.
