I don't know how to set the GPO to deploy the patch to the different ou. Wsus and sus are the same?

Does anyone know how to set the GPO with AD?

You should have received the updated .adm file with the wsus download. On the server in question, it was placed in %windir%\inf - copy the wsus .inf file from that server to one of your DC's, open the GPO you want to add the settings to, and under Computer Configuration right-click on Administrative Templates, and choose add/remove templates. Click the Add button, and you should see the .inf you copied over. Select the INF, and the settings will now be under Administrative Templates in your GPO (somewhere in the network subtree, I believe).
