OCS 2007 설치시 Err. LOG 및 해결 방법

퍼온글 : Happy Days: OCS 2007 and Exchange 2007 Installation

During my demo environment installation (OCS and Exchange 2007), I got a few blockers that I couldn't find documented on the Internet. Maybe, it could be of your help. Here they are:

OCS Deployment:

Failure [0xC3EC7924] Schema definition for the requested Active Directory attribute isn't available. Please ensure local ADSI schema cache is up-to-date.

This problem occurred during the Deployment step of the OCS installation. Every AD schema preparation step ran successfully prior to this one. Checking the logs, it turns out that the AD schema class "Phone Route Usages" doesn't exist or there's a problem reaching it. The solution was to delete the schema cache file on the local server. The schema cache file is stored under C:\Windows\SchCache and this is used by ADSI to avoid the roundtrips to download the schema for every AD request. Simply delete the files stored in this folder (every domain has its own schema cache file) and re-run the installer.
