Microsoft has provided a fix for this issue. The fix (ocsasnfix.exe) is available at http://support.microsoft.com/kb/974571 Doug Deitterick–the person whose blog is referenced in the update link above–passed information about this fix on to me.

Good news is the fix works like a charm.

Thanks for the comment. I was expending hours looking to some dung error messages and would never find it. I “love” when MS does it to their own products.

Hi Lukas,
I too installed the offending KB974571 and OCS 2007 R2 is broken (only OCS Application Host service started). However, uninstalling KB974571 did not fix my OCS.

The next error after event id 12290 is event id 12299 with the following details:

“The service is shutting down due to an internal error.
Error Code: C3E93C23 (SIPPROXY_E_INVALID_INSTALLATION_DATA)
Cause: Check the previous entries in the event log for the failure reason.
Resolution:
Check the previous event log entries and resolve them. Restart the server. If the problem persists contact Product Support Services.”

Any idea how to fix my broken OCS?

THANK YOU!!!!! I was pulling out my hair this morning. I knew it wasn’t an issue with an evaluation version so I naturally assumed it was something to do with updates from Friday evening. I really appreciate that you freely shared your knowledge. It made my life much easier today.

Mike,

They did. It’s just that my blog post was the first mention on the web about this issue, and thus at the top of most search results. I linked to the official MS statement of this issue at the top of my post – in bold ;)

I wish Microsoft would make this a bulletin. This answer fixed our issue.
