Windows Vista includes a new technology called ReadyBoost, which is designed to speed-up your system by caching disk reads into flash memory.  Originally, I read this feature was intended for the upcoming hybrid drive technology (more info here), but I recently learned ReadyBoost will also work with other types of flash memory like a USB drive.  Here are some interesting facts about ReadyBoost: [more]

  • Caches only disk reads, so the flash device can be removed at any time
  • Cache is encrypted using AES-128
  • Minimum requirements is 256mb of space, with the device capable of 2.5MB/sec for 4k random access reads and 1.5MB/sec for 512k random writes
  • Microsoft recommends matching the capacity of the flash device to the amount of system memory
More information is available at http://www.extremetech.com/article2/0,1697,2017844,00.asp or http://blogs.msdn.com/tomarcher/archive/2006/06/02/615199.aspx.

When you insert a flash drive, Vista will test the device and give you the option of using it for ReadyBoost.  Properties on the drive shows a ReadyBoost tab with an option of controlling the amount of space to be used.


 

When deploying a Microsoft cluster with shared disk resources on a san, be sure that the SAN controller supports “capacity extension” technology.  If this is not supported, it will be impossible to add storage capacity to the existing disk resource.  A new resource will have to be created. [more]

Even after capacity is extended on the shared disk resource,  Windows will not recognize it, because shared disk resources are basic disks, and cannot be converted to dynamic.  The extra capacity can be utilized only by extending the partition using the diskpart command(use caution!).


 

To test email, send a help message to a mailing list server, [email protected], for example.  Just include the word help in the body of the message.  Another good place to send email (with anything in the subject and body) to is [email protected].  This sends a message back with a report about your spf configuration and includes details about your original email.


 

As of IOS 12.3(1), Cisco introduced support for enforcing a minimum number of password characters and sending a syslog message after a specified number of failed login attempts.  Enabling these commands will help banks comply with regulations and their own policies as well as improve the security of their Cisco IOS devices.  I have not found similar commands for CatOS or PIX OS yet. [more]

security passwords min-length <length>

  • global command that sets the minimum password length for user, enable, and line passwords.
  • Default is six, but it should be configured according to bank policies.


security authentication failure rate <threshold-rate> log

  • global command that sets the number of failed login attempts (without at least a 15-second delay) before a syslog message is generated
  • Threshold value can be 2-1024.  A value of 1 will not generate any syslog messages.  Default is 10, but should comply with bank policies.

 

Microsoft plans to deliver their latest version of Internet Explorer (version 7) as a high-priority security update via Automatic Updates (AU) and the Windows Update and Microsoft Update sites. The IE update will be available shortly after its final version release (expected within the next few weeks).

Internet Explorer 7 Release Candidate 1 (RC1) is currently available from Microsoft's website (http://www.microsoft.com/windows/ie/downloads/default.mspx). IT Administrators should begin installing and testing this new version of IE for application compatibility.

Microsoft is providing a Blocker Toolkit for enterprise customers who want to block automatic delivery of IE7. The Blocker Toolkit can be downloaded from Microsoft's Download Center at:

Microsoft has recently released information about a critical vulnerability found in their Exchange Server product. The vulnerability, if exploited, could allow a remote attacker to execute arbitrary code and gain complete control of the Exchange mail server.

The following Microsoft Exchange Server products are affected:

  • Microsoft Exchange Server 2000 with the Exchange 2000 Post-Service Pack 3 Update Rollup of August 2004
  • Microsoft Exchange Server 2003 Service Pack 1

A vulnerability has been discovered in Microsoft's Picture and Fax Viewer that allows arbitrary code embedded in image files to be executed without user intervention. This vulnerability can be exploited by simply loading a picture from a malicious website or e-mail message. Microsoft is aware of the problem and is working on a fix. Until an update has been released, users are encouraged to exercise extreme caution when browsing the web or opening e-mails with embedded pictures. It is also important that Anti-virus and Anti-spyware applications be kept up-to-date.


 

Following daylight savings time change, some backup applications will modify the scheduled backup job start time to preserve a 24-hour time gap between the current and previous day’s job. In particular, CoNetrix has determined Veritas’ Backup Exec version 9.x and greater will push the scheduled backup job back one hour from the original start time. For example, a backup job typically scheduled to start at 10:00pm on Monday will start at 11:00pm on Monday. This may cause conflicts with overlapping scheduled jobs. Veritas states that the problem should automatically correct itself following the first run after the time change. Users should check their scheduled backup jobs to ensure the start time for each job is correct.


 

APC's PowerChute Business Edition 6.x must be upgraded to 7.x. PowerChute software manages the UPS system (Uninterruptible Power Supply).

If you are still using any version of PowerChute Business Edition 6.x, you may experience various computer issues. The most common symptom is that servers are hanging or booting slowly. Other symptoms may be a delay while trying to access the Control Panel or an inability to stop the PBCE Services.

Due to expiration of the Sun Java Runtime Environment certificate, versions 6.x of PowerChute Business Edition will cease to operate normally as of July 27, 2005. Failure to upgrade will result in PowerChute Business Edition no longer providing monitoring and graceful shutdown of your system. In order for PowerChute Business Edition to remain functional, users must upgrade to any version of 7.x. [more]

CoNetrix recommends customers take the following steps to ensure they are not affected by possible problems resulting from the expiration of the Sun Java Runtime Environment certificate:

  • Logon to your servers as an administrative user.
  • Goto: Start -> Settings -> Control Panel -> Administrative Tools -> Services
  • Check the list of services for APCPBEAgent and APCPBEServer

If the services exist:

  • Right click on the service name and goto Properties
  • On the General tab, change Startup type to Disabled
  • Click OK and close the Services window
  • Upgrade to PowerChute Business Edition 7.x
