Most of our Symantec Endpoint Protection clients are alerting that the definition dates are old (we reduce the alert time to less than the default 30 days). These alerts are coming in through the desktop client and also through both of our monitoring systems. Apparently Symantec are aware of the issue (see “The date of the definitions in Symantec Endpoint Protection clients and Symantec Endpoint Protection Manager remain at Dec 31 2009”) and their definitions cannot have a date in 2010. Therefore their work around is to push out new updates with a date of December 31st 2009 and they are just increasing the version number until engineering come up with a patch to fix the issue of not accepting dates in 2010.
I sure hope that their update plan works better than our most recent upgrade that meant we had to reinstall the client by hand at every desktop. None of the upgrade processes would work.
