I tried to connect to a WinXP machine on my network that is in the same domain as my other 2 XP PCs and has folders shared for use by everyone. But, when I tried to connect to that PC to view the shared folders, I got a message that said "XXXXXXX is not accessible. You might not have permission to use this network resource. Access is denied." When I searched for a solution, I found a KB article at Microsoft (http://support.microsoft.com/kb/913628) that explained that the problems could be due to the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous" setting being set to "1". The article said to set this to "0" to allow anonymous file sharing on the local network. So, I set the "restrictanonymous" setting to "0" and rebooted as the KB article said. But, when my PC rebooted, I still had the same problem and the "restrictanonymous" setting was back at "1". I tried to change it several more times - each time I got the same result. Finally (thinking that something may be changing it before logging off) I reset "restrictanonymous" to "0" and did a hard reboot by hitting my system's restart button. But, again, the "restrictanonymous" setting was back to "1". I even tried disabling the XP firewall (no reboot) and got the same error. Is NOD32 doing this? What could be resetting my "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous" setting to "1"?
