Microsoft Fixes VPN Flaw in XP SP2
The bug, which had been reported soon after SP2's release, caused VPN connection errors.Microsoft has issued a formal fix for a problem in Windows XP Service Pack 2 that appeared almost immediately after the updates release. The problem, which affected many VPN users, causes errors when programs attempt to connect to loop-back addresses other than 127.0.0.1. Service Pack 2 blocks all such addresses; users receive an error message saying that they cannot establish a connection.
Microsoft had issued a hotfix for the problem last month, but the new update is more thoroughly tested and available to all without having to go through Microsoft Product Support Services.
