Critical Windows patch may wreak PC havoc
A Microsoft patch meant to fix critical security flaws in Windows 2000, Windows XP and Windows Server 2003 is causing trouble for some users, the company said Friday.
The patch was released Tuesday to fix four Windows flaws, including one that experts predict will be exploited by a worm in the coming days. The flaw, tagged "critical" by Microsoft, lies in a Windows component for transaction processing called the Microsoft Distributed Transaction Coordinator, or MSDTC.
Installing the patch can cause serious problems, Microsoft said in an advisory posted to its Web site Friday. The patch could lock users out of their PC, prevent the Windows Firewall from starting, block certain applications from running or installing, and empty the network connections folder, among other things, the software maker said.
