See Microsoft Support Online article Q245329 for details.ĭo you have Windows 9x systems configured as Systems Management Server (SMS) 2.0 or SMS 2.0 Service Pack 1 (SP1) clients? If so, these clients might hang when a user opens an email attachment. Microsoft has released an update for Intel and Alpha platforms that performs the year conversion properly you must call Microsoft Support for the update (it’s not available for public download). The Convlog utility included with Internet Information Server (IIS) 3.0 incorrectly converts the year 2000 to the year 2028. You can find documentation of this security concern in Microsoft Support Online article Q244995. To keep your system secure, check this Registry value (and adjust it if necessary) each time you apply or reapply a service pack. ![]() To enable base system object protection, you must set ProtectionMode to a value of 1. When I checked ProtectionMode, it was set to 0. My system has two Session Manager keys, and ProtectionMode resides in the first one. If ProtectionMode has a value of 0, base system object protection isn’t enabled and a user can potentially access system files that run in an elevated privilege mode not subject to typical security controls. The Registry value entry ProtectionMode (data type of DWORD), which controls access to certain core OS components, resides in the key HKEY_LOCAL_MACHINE\CurrentControlSet\Control\Session Manager. Service packs can remove or reset a Registry value entry that protects base system objects against unauthorized access. Let's hope we see a post-SP6 Winlogon fix in the near future. This problem is one good reason to hold off on deploying SP6 to end-user workstations. To work around it, use the three-finger salute (Ctrl Alt Del) and click the Logoff button when the Windows NT Security window appears. According to Microsoft, the logoff problem relates to changes introduced in the newest version of Winlogon. This behavior must be intermittent because I didn't experience it on my SP6 system. Here’s the first issue to appear since the release of Service Pack 6 (SP6) a week ago: After you upgrade to SP6, the screen grays and the mouse pointer remains an hourglass indefinitely when you log off via the Start menu. You’ll find the Intel version here and the Alpha version here. The good news is that you can download the TCP/IP hofixes directly from Microsoft’s Web site. This vulnerability exists in Windows NT 4.0, Enterprise Edition BackOffice Server 4.0 and 4.5 and Small Business Server (SBS) 4.0 and 4.5. Microsoft Support Online article Q243835 indicates that NT Server and BackOffice Server TCP/IP initial sequence numbers are predictable, which opens the door for a malicious user to access a system via IP address spoofing or session hijacking. When a Windows NT system sends TCP/IP packets to another computer, each packet contains a sequence number that the destination computer uses to reassemble the packets in the correct order before processing the contents.
