Virus scan fails on certains machines

I run a scheduled AV scan on on the machines in the network (about 45) once a week. About 10 of them fail to do the scan regularly. (and yes they are on)… The Result is FAILED (0x000005B4). Any thoughts as to the issue?

If I’m not mistaken, error 0x000005B4 says that ADNM couldn’t contact the computer - usually because the computer is turned off.

(and yes they are on)…

I’d say that if the computers are on, they might be blocking the ADNM server with a firewall.
