I have a machine that has been working fine for almost 3 years, WHS original box. About a week ago the clients stopped updating from the server with the error "File not found on server" I've checked all the settings in the ERA console and it all looks good. I've also uninstalled what was a pretty old version and downloaded and installed the latest ERA Server and Console and setup the updates mirror again. I've also updated the clients to the latest NOD32 and the update issue is still there. What else could be going on?
