Problem with applying security patches to CCM from MS
One of my customer applied security patches to both publisher and subscriber ccm servers from Microsoft directly.After he reload publisher, he got tons of error messages in application log. The subscriber hasn't been reloaded yet. So far phone system is still working on subscriber. How we can do next?
Remove all patches and apply the lastest Cisco IPT OS(currently version is 2000.2.7sr4)? Or just apply the latest Cisco IPT OS anyway, it will clean the system up? We really don't want get thing worse.

There is a good practice - when you apply any patches or do upgrades, just pop one harddrive (sure, if you have RAID). After the installation is done, and you completely sure that everything is OK, you may just push HDD back, and it will re-build RAID. If installation is failed, you may shut down the server, pull the "bad" HDD, push the "good" HDD, and power the server up. It will boot up as if you never installed that update. Then, after a couple minutes, you can insert "bad" disk back, and it will be overwritten with the "good" image.
Another "gold rule" - do not install any patches directly from the Microsoft. Cisco patches come with a little delay (may be a couple days), but they are verified to be "compatible" with the CallManager.
