그런데, 별다른 오류 정보가 없군요. ^^ 어쩔 수 없이 시키는 대로 이벤트 로그를 살펴봤습니다.

오호... 그나마 좋은 정보가 나왔군요. ^^
그렇습니다. 오류가 난 호출은 BasicHttpBinding이었으나 그 서비스가 함께 등록된 net.tcp 바인딩에 대한 등록이 Web Site에 없어서 발생한 것이었습니다. 이런 경우, 다음의 2가지 설정에서 net.tcp를 등록해 줘야 합니다.
[그림 1: Web Site의 Binding 정보에 net.tcp 추가]
[그림 2: Web Site의 고급 설정에서 net.tcp 프로토콜 추가]
