Symantec endpoint protection client not updating from the server
Relative definition age can be determined by the revision number.While this issue is being resolved SEP definitions are being built outside of the normal build process.Since 12/31/09 rev xxx is considered the latest content available to the SEPM, a client will not update to a content revision later than the highest numbered revision available on this date.
This includes all Security Content updates - including Antivirus definitions, Proactive Threat Protection (PTS) Truscan definitions, and Intrusion Prevention System (IPS) definitions.
This document will be updated as soon as more information becomes available.
Once a solution is available it will be posted to Live Update, and SEPM/SPC will download and apply the update automatically.
Once patches are available and this temporary problem has been corrected by Symantec, details will be posted to this KB article.
Please also note that once the SEPM servers have been patched, the clients should remain configured to download content Live Update for at least 3 days to ensure that they will get delta definitions from the SEPM server .
