error when trying to install topology export on an edge server

Hi,

I'm getting the following error message when trying to install a topology export onto an edge server, its the same as described in this thread /Forums/lync/en-US/4be9f65d-58c2-454b-a497-71f4c7645b0a/command-execution-failed-an-error-occurred-when-add-rtcuniversalconfigreplicator-to-rtc-local , and there is a comment that mentions that domain membership getting in the way. Our edge server is in the DMZ so it isn't domain joined and the fix to our error message is to add the admin account to CSAdministrator, RTCUniversalServerAdmins and RTCUniversalGlobalReadOnlyGroup. But these groups only exit in our AD and not on the edge server.

can anyone help?

thanks,

Mark
