Symantec antivirus server not updating
If a client is not receiving updates automatically, follow this process.
If you have a support contract with them - I really suggest you contact them instead.About a month ago, the Virus Definition File version date stopped updating and hasn't updated since - 3/26/2012 rev. The automatic update has continued to run everyday, downloading the latest definitions, but not updating the version date in the client. Sometimes it downloads an update successfully and other times it says the virus definitions are up to date.If I run it again after a successful download, it will always say it's up to date.See Mitigating network overloads for client update requests.To help mitigate the effect of downloads on network bandwidth, download content randomly so that not all clients get updates at the same time.
