Users began having problems implementing a Microsoft patch issued to fix a hole in the Windows 2000 operating system.
According to alerts posted on the SANS Internet Storm Centre Web site, the patch is detailed in Microsoft Security Bulletin MS05-051 and designed to address a total of four separate vulnerabilities, of which two are categorised as "critical" for users.
The problems reported by users include an inability to use the Search tool in the operating system's Start Menu, a blank screen upon log-in to the Windows Update site and disruption of Symantec LiveUpdate virus-updating facility.
Early discussions with Microsoft engineers suggested the problems apply to users with specific NTFS permissions, affecting their C:WinntRegistration folder, which cannot be written to by COM+. Microsoft is expected to elaborate on the problems this week.
The need to make available a whole raft of patches may be behind Microsoft’s patch problems. Over the last few weeks, Microsoft’s reluctance to deliver patches until they were
ready and tested provoked comment. Perhaps these problems, if confirmed, will explain Microsoft’s reluctance. It may be that the number of users affected turns out to be limited, though any users who install patches that do not perform as anticipated, should be miffed.
