XP Update Blocks Net Access for Some
Because an update designed to improve the operation of VPNs running on Windows XP machines blocks some users from accessing the Internet, Microsoft has yanked it off its download site.Microsoft Corp. on Tuesday yanked an update for Windows XP off its download site after it became clear that the software was blocking some users from accessing the Internet. The update, which is not a security patch, was designed to improve the operation of VPNs running on Windows XP machines. It made some changes to the way the machines use IPSec encryption and the Layer Two Tunneling Protocol when theyre behind devices such as firewalls that perform network address translation.
The changes were designed to bring the way that XP handled IPSec and the tunneling protocol into compliance with the Internet standard.
