After trying of deploying OCS 2007 R2 group chat server, I can't start the Office Communications server Audio/video conferencing service and the office communications web conferencing service on server. OCS was ok untill yesterday, and now i've got that error, i really don't know why.
Error 1053 cannot start the service, the service did not respond to start or control request in a timely fashion
Basically I did the following steps without any success:
First, I deactivated the OCS SE services (in particular order below)
Second, uninstall OCS EE services (add/remove programs)
Third, wait for AD to replicate the changes (typically 15-60mins).
Fourth, reinstall OCS EE
Fifth, Deploy the pool, and install web components, etc
Sixth: Tried of activating the application from the OCS 2007 R2 tools and no luck
