Just bought Eset Nod32 Business edition. Downloaded the client, the console and RAS. Installed the client on the computer that is going to function as the updateserver. This computer i called Nodserver. Installed RAS on computer Nodserver. Installed the console RAC on my administrator computer called "Automatisering". I read the manuals, a lot of threads on this forum etc. I read everything for 3 complete days but i cannot get the clients to update from the mirror "Nodserver" I activated the mirror within RAC, pointed the clients to mirror "Nodserver" etc. I think i tried everything possible now but i cannot get it to work. We use a router that is administrated by our provider, we don't have access to this router ourselfes. All ports are closed on this router except the necessary ones for internet and email etc. Could this be the problem? I can add clients to RAC so there must be a good connection between computers and our network is up and running fine. Is the http method dependant of the internetrouter ports being open? I thought for our networktraffic this is not necessary? Thanks for any answers.
