For those that use LCS or OCS in you environments, I wanted to make you aware of a potential issue with one of Microsofts  latest security updates that could cause an outage by showing LCS or OCS running as an evaluation version and then noting it as expired.

 The hotfix (MS09-056) is detailed @ http://www.microsoft.com/technet/security/bulletin/ms09-056.mspx
