Aggornamento KB951748 incompatible with Zone Alarm 
For several days, was issued a new aggiormaneto " KB951748 " by Microsoft for the XP OS, many of the users who had installed ZoneAlarm as a firewall, found themselves with an active internet connection but not working. The problem is incompatibility between a firewall and the update released by Microsoft.
To resolve this problem you must temporarily disable the firewall (To allow navigation), connect to the site of ZoneAlarm, and download the latest version of the firewall, and proceed with the installation, at the end after the reboot, everything back working.
Windows XP and Windows XP service pack 3 
a few weeks ago was released by Microsoft, the long-awaited "service pack 3," which seems to go to correct and improve the system with some 1100 updates.
The service pack 3 is not included in Microsoft's' Windows Update, just because at the beginning, Microsoft became aware of a bug on the compatibility with "Microsoft Dynamics RMS," but the problems are not over, for owners of AMD, there are underlying problems of continuous reboot the machine and system errors (the famous blue screen).
Having had the opportunity to try the "SP3", I noticed a greater difficulty in managing the network and share files and printers on the local network.
currently do not recommend the change to the new service pack as the ultimate solution for now is maybe better to try it on a machine to see how it works (do not recommend to try it on the PC that used to work).
That is, as usual we are waiting for the problems are resolved by Microsoft.
