Our OCS 2007 R2 server (W2K8 + SQL 2008) has been working OK for a few months. A few days ago it was patched via Windows Update and as the result all the OCS services (except the application host) failed to start.
I discovered that many people also experienced this issue due to MS Crypto API security update KB974571. I then uninstalled KB974571. However, OCS services never came back up. I then applied almost all OCS October 2009 patches. Also applied ocsasnfix.exe. No Joy. Any idea how to fix this?
