I am new to Nod32 (switching from Avast). I have installed Nod32 v3 on several workstations and everything seems great. However, today I installed a new server (Windows 2003 Server Standard) for a client and I had preinstalled Nod32 Business Edition on the server prior to introducing it to the network. From the 5 workstations on the network, I had no problem accessing and opening files on network shares on the server, but if I tried to create or move new files to the network shares, the server would become almost completely unresponsive and kick all the workstations offline. I would have to restart the server in order to get everybody connected again. Grasping for straws, I decided to uninstall Nod32 and the problem seems to have gone away. I am not 100% sure that Nod32 was causing the problem but for now it is looking kinda like it may have been. All of the workstations are running Avast Professional (haven't switched them to Nod32 yet) Could that possibly be causing a conflict? Any ideas? I am scared to even reinstall Nod32 on the server at this point.
