WARNING about KB974571 and Event ID 12290

  • Article

We've found that the update released by Microsoft on 13th October 2009 to fix CryptoAPI issues will cause OCS services to fail. We are also seeing reports of client side issues.

The server will log event ID 12290 which says:

"The evaulation period for Microsoft Office Communications Server 2007 R2 has expired. Please upgrade from the evaluation version to the full released version of the product."

The server will then log event ID 12299 with the error code:

"C3E93C23 (SIPPROXY_E_INVALID_INSTALLATION_DATA)"

The KB article can be found at: https://support.microsoft.com/kb/974571

To fix the issue, remove the patch and restart the server. Spread the word on this one!
