Exchange 2007 SP1 Rollup 1 and TransportService 12011

A few houers ago, i installed the update rollup for the SP1. After the installation all exchange services were deactivated. There was no big deal to bring up the services again but despite a reboot i got the event 12011 form TransportService logged ('the domain does not exists, or the connection could not be established'). After some research i found out that an equal problem exists since sp1 and that there is no known yet.
Well, it sucks to have stupid errors again but the event does not impact on the functionality as known.
