Hello. I have a LAN with ~70 machines. RA Server is installed on one of the machines. When I want to install NOD32 on one of the other machines on the network, sometimes RPC process on target installation PC fails. And PC reboots after one minute. However NOD is installed after reboot. I also can't get version number of OS and NOD32 from workstations. It says "RES Error" in the RA Console. Is this because I don't use Domain in the Network? It's just simple Workgroup.
