Your question is unclear to me. Could you provide a little background? Update which software. macOS? Server.app?
The ADP000 code is something that the Apple Diagnostics software can display—that code indicates no hardware problems have been detected—but that’s unrelated to macOS Server.
Are you having issues with your server? If so, coukd you describe the problems you’re encountering?
Diagnostics can sometimes miss hardware problems, unfortunately.
