I have been trying to install Office Communications Server (OCS) 2007 R2 Standard Edition for a few days now without success.
During the server install process (after the schema has been extended), a warning shows up in the activation logs of every role (Standard Edition Server, Web Components Server, Web Conferencing Server, Audio/Video Conferencing Server, Application Sharing Server, and Application Host).
The warning on the main Deployment Log states:
[0x03EC796D] Wizard was successful, but one or more warnings occurred during execution of the wizard. Please check the log file for more information.
The warning within each activation log states:
[0x03EC78E4] More than one DNS records are found for the pool FQDN. Please validate the pool's DNS registration.
A note about the DNS Record Count: 3 is also in the log.
After trying for many hours to get this to work, the solution is simple, but it isn't ‘nice'.
Office Communications Server 2007 does not support network interface controller (NIC) teaming. Sounds crazy, right? Good luck finding this little tidbit documented anywhere.
[UPDATE] I have been told (by a Microsoft rep) that Microsoft does support NIC teaming, but I haven’t found any documentation that points to the correct answer.
