Symantec antivirus 10 not auto updating
If a client is not receiving updates automatically, follow this process.
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.That meant the clients couldn't connect to the Live Update server because of firewall rules and it would silently fail.You can check by searching the DNS Cache for the server name and checking the IP C:\ipconfig /flushdns and fix up your DNS zone file.We had some problems recently where Live Update was installed on a W2K Domain Controller with LAN and Internet NICs and as a result the Active Directory DNS zone for the domain kept being updated by Net Logon.It would add the public IP addresses into the zone file against the LAN name of the server and as a result some LAN clients would get given the Internet IP address (because MS DNS server uses a round-robin process to returning multiple IP addresses for load-balancing).
And new Vulnerability Protection blocks security holes in your PC’s operating system, applications, browsers, and browser plug-ins to prevent hackers from exploiting them.
