#title 원격 서버간 메시지 주고 받기
[[TableOfContents]]

==== 환경 ====
 * Source Server : 192.168.89.79
 * Target Server : 192.168.89.80
 * Active Directory 환경이면 쉽게 구현이 가능하지만, 어디 환경이 그리 녹녹한가? 그래서 이 예제는 인증서 기반의 메시지 주고 받기를 해 본다.
''"주의사항" 반드시 순서에 맞게 구현을 해야 한다. 인증서 기반의 원격 서버간 메시지를 주고 받기가 생각보다 쉽지 않다.''

==== 시나리오 ====
물리적으로 분리된 원격 서버 Source Server와 Target Server간에 메시지를 주고 받는다. 두 서버는 Active Directory에 Join되지 않은 환경으로 인증서 기반의 인증으로 원격 서버간의 메시지를 주고 받는다. 

==== <Source Server> 마스터키 생성, 인증서 기반 인증을 위한 인증서 생성 ====
{{{
--Configure the transport security.
USE MASTER
go

--Create a master key in the master database.
--DROP MASTER KEY
CREATE MASTER KEY ENCRYPTION BY password = 'MasterKeyPassword'
Go

CREATE CERTIFICATE ctfSourceServerMaster
WITH SUBJECT = 'SourceServerAuth'
ACTIVE FOR BEGIN_DIALOG = ON

BACKUP CERTIFICATE ctfSourceServerMaster
TO FILE = 'C:\Certificates\SourceServer.cer';
GO
}}}

==== 인증서 서버간 복사 ====
각각의 서버에 인증서가 생성되었을 것임. SourceServer.cer를 TargeServer의 c:\certificates 폴더에 복사하고, TargetServer.cer를 Source서버의 c:\certificates 폴더에 복사한다. 그리고 다음 스크립트 수행
