Is there not a case for posting, at the top of the Beta Forum, a list of interim fixes for the current build.
e.g.
ccSvchost errors seem to be caused in the main by Antispam and turning it off helps alleviate some symptoms such as NIS stopping sporadically.
Network errors and uninstall errors caused by Network List Service not started and set to manual.
If these were post in a prominent position it would help alleviate some of the load on Gurus and Symantec Employees and also give users some satisfaction that they have found their own cure (always helps to think you've solved your own problem).
Just a thought for future Beta builds.
