For now, hold off on installing KB 974571 on OCS 2007 R2 servers (and possibly R1)

I didn't discover this one, so I'm just the messenger passing word on - KB 974571 (part of Patch Tuesday today - specifically related to Crypto-API/ASN1) will make OCS think it is an evaluation version that has expired. Uninstall KB 974571 and OCS works again. You will want to apply the KB once an updated patch, or an updated patch for OCS becomes available. I've verified this problem in my lab too.

Originally documented here.

Confirmed on OCS R1 here also.
Important:
You must also remove this update on all your Edge servers as well as on your front-end servers...

Thanks

Yeah, confirmed here too. Let's see if they find any solutions to update that patch without breaking OCS.

This also breaks LCS 2005
