SnapManager Exchange or SQL Service failed to start

or why .NET-Applications need long to start: "A common cause that I have seen often recently is Certificate Revocation List (CRL) checking when generating Publisher Evidence for Code Access Security (CAS)."[1]

In my case the Exchange Sever didn't had anymore direct access to the internet. The CRL checking during the SM Serverice Startup failed. This took longer than 30 seconds and causes the service start to time out. Adding some lines to the SnapMgrService.exe.config prevent the service to do the online CRL check. No further timeouts, services starts.

Same issue some month's later with a SnapManager SQL installation. Good to have a cheat sheet for the most wired thing online.
