A common problem we see at client sites (particularly those running IBM hardware for some reason) is when Exchange 2010 Update Rollups are running, the server will blue screen in the middle of the update, leaving the various services in disabled and broken states, and effectively killing the functionality of the server. Microsoft never seems to have acknowledge or resolved this issue, and it can be highly frustrating.
Thankfully the solution is scriptable ahead of time, if and when it happens! Also - always be sure to run your Rollup MSP files from an elevated command prompt or they definitely will fail.
What happens is the Update Rollup installer disables services and then does not re-enable them, after a crash or problem.
Save these as batch files on the server and run them after the server reboots. The first script assumes the MBX, HTS, CAS, and UM roles are all installed on one box; the second script is for the Edge Role. Customize to fit your server’s role.
