Mike, I too have tried to contact a Navy officer whom I had once met years back. I had no luck with the Navy personnel locator services because all I knew was the guy's first and last name, rank, and job (from seven years ago). The locator services wanted more detailed information than what I had to go by. I eventually established contact with the person by calling out the the NAS where I last had knowledge of his presence. I had to speak to at least ten different people, but I finally got in touch with the guy. My advice to you is to get on the horn if the locator services blow you off or make you wait around.
