Hi, Since installing NOD32 I have started getting errors when I boot up my computer. The desktop will start to load, the NOD32 box will appear in the middle of the screen, and then nothing will happen for a few minutes, no network connection icon appears in the taskbar, and when it does finally, it shows as having no connectivity. A look in the event viewer gives the following error messages: 'TimeProvider NtpClient: An error occurred during DNS lookup of the manually configured peer 'time.windows.com, 0x1'. NtpClient will try the DNS lookup again in 15 minutes. The error was: A socket operation was attempted to an unreachable host. (0x80072751)' Or if someone else (in our network of 3) has their machine switched on I get an error message saying that 'The browser was unable to retrieve a list of servers from the master browser............'. Can anyone help with this? I don't know much about networking to be honest, but I didn't have any trouble with these errors until I installed NOD32. Thanks for any help.
