I would point out that all three respondents have been helpful here.
Pawel, at the risk of sounding ignorant (in this case I truly am!), what is the procedure for installing as automanaged? I received instructions to install SEPM, but not standalone (automanaged?). If I just uninstall the SEPM will that "force" the computers to go to automanaged, or do I have to uninstall SEP on all machines and reinstall?
John, thank you for instructions to reduce the LU cache and purge the 700MB stored there. My server was set to 872 MB cache before I reduced it.
Sandra, yes by "normal" I was referring to consumer product Norton Antivirus. When I tried to install the product on the server with Windows Server 2003 OS, it refused to install with message that the OS was not supported. That is when I called your sales department, and they recommended the SEP. Prior to purchasing SEP, I had been using Mcafee antivirus. It installed OK, but was not actually protecting (!!!). I have always been very careful about opening emails (even from customers), so it took about three years before I picked up a trojan that wiped out the boot sector. Repairing the boot sector failed and I had to set the entire system back up. Thank God for backups! Mcafee's response was unsatisfactory, so I "fired" them and purchased Symantec, with which I am satisfied.
