Symantec Endpoint 1. RU1 Return Error code 4. Hello. I have two version of Symantec AV solutions running on the same net. One is a legacy product Sym AV 1. It has been working for a while now. About 8 years. But we recently installed sym 1. I looked over the sym documentation but i havent found anything i am missing. The issue is that I cannot update the virus definitions on the newly installed one endpoint 1. We do have a proxy in the network ISA 2. In the proxy tab in system settings of Symantec endpoint I have tried every combination possible entering the PROXY credentials. FQDN, ip, hostname. I tried using the user account credentials for proxy authentication. I also tried using the domain admin credentials. Please keep in mind that my legacy Sym product works ok and that I have the same firewall policy in ISA that I have for the legacy Sym product as well.
