I am having an issue installing a managed version of SEP onto client machines. I used to have no problem, but recently every single computer I try to deploy to shows up in unknown computers and the installation always fails. I know machines only show up in unknown if there is a problem with yoru credentials, but I am 100% sure that my credentials are fine. The client machine I am trying to log into is right next to me and I can log in with no problems. I am also using a domain admin account, and have even added myself as a local admin on the machine just on case. Does anyone know what else could be causing the machines to show up in unknown computers? I have been forced to install unmanaged versions of symantec on the last several machines, but I recently just got an additional dozen machines and really cannot continue using unmanaged versions on all of these. Any help would be GREATLY appreciated!!! Thank you.
