It is necessary to know which hosts on which ports are needed to be opened up in the firewall/proxy in order for the Antivirus and Antispam definitions to be successfully downloaded.


Example of errors:
"1813  The process launched by the LaunchEx command returned....."
"1819  The Proxy Server requires authentication and we are not giving it any authentication."

Below are the requirements

Hostname Protocol Port TCP 80 TCP 80 TCP 80



If Premium AntiSpam will be used additionally it is needed

Hostname Protocol Port TCP 443 TCP 443


There are workarounds offered by Symantec in order to bypass the above requirements going through a proxy. However these workarounds are only provided "as is" since they are depended on the Operating Systems System accounts capability and restrictions to download which can not be troubleshot by Symantec as it is outside the support boundaries.
