Two more beta exams! (71-654) Windows Essentials EBS, (71-660) Windows Internals

I love Trika! She’s such a wealth of knowledge, information, lolcatz and a number of other sillie things!

In this episode, we cover two (more) beta exams.

71-654 – TS: Windows Essential Business Server 2008, Configuring
The promo code is “EBS08
The beta is initially scheduled from 7/22 to 8/12.

About EBS: “Windows Essential Business Server 2008 combines software for management, messaging, and security features into one integrated server solution that will help customers increase the manageability and reliability of their IT systems, and boost businesses productivity and growth.”

This credential is designed for information technology (IT) professionals working in or consulting with medium sized businesses that use Windows Essentials Server 2008. A candidate for this exam should have at least one year of experience deploying, configuring, and managing network solutions in an environment with the following characteristics:

* 75+ company network connections
* Company networks with Internet connectivity
* Individual users or user groups that connect to the company network from remote locations
* Messaging (Internet, and Exchange)
* Anti-spam

And the second (and cooooolest one)

71-660: TS: Windows® Internals
The promo code is “WINT
Beta exam period runs: July 21, 2008– August 5, 2008

About this Exam

This exam validates deep technical skills in the area of Windows Internals. Including troubleshooting operating systems that are not performing as expected or applications that are not working correctly, identifying code defects, and developing and debugging applications that run unmanaged code or that are tightly integrated with the operating system, such as Microsoft SQL Server, third party applications, antivirus software, and device drivers.

Audience Profile

Candidates for this exam are engineers, developers, or IT staff who work with Windows at a level that requires Windows Internals knowledge. Candidates for this exam are typically in the upper echelon of the technical staff at their companies. These individuals typically hold such positions as escalation engineer, technical lead, and software design engineer. Their level of knowledge spans products both inside and outside the Microsoft Corporation. These individuals are involved in resolving problems that require deep understanding of Windows Internals rather than problems about planning and infrastructure development or how to use or configure a product that runs on Windows.

When security best practices collide (Crippling iSCSI in Windows)

As a security guy, I can tell you – There are a lot of really good security best practices to be applied across all systems, applications, servers and a world over. But when implemented unchecked – Problems will arise.

What I am talking about specifically is this little doozy – EnablePMTUDiscovery

Value name: EnablePMTUDiscovery
Key: Tcpip\Parameters
Value Type: REG_DWORD
Valid Range: 0, 1 (False, True)
Default: 1 (True)

The following list describes the parameters that you can use with this registry value:

  • 1: When you set EnablePMTUDiscovery to 1, TCP attempts to discover either the maximum transmission unit (MTU) or then largest packet size over the path to a remote host. TCP can eliminate fragmentation at routers along the path that connect networks with different MTUs by discovering the path MTU and limiting TCP segments to this size. Fragmentation adversely affects TCP throughput.
  • 0: It is recommended that you set EnablePMTUDiscovery to 0. When you do so, an MTU of 576 bytes is used for all connections that are not hosts on the local subnet. If you do not set this value to 0, an attacker could force the MTU value to a very small value and overwork the stack.

    Important Setting EnablePMTUDiscovery to 0 negatively affects TCP/IP performance and throughput. Even though Microsoft recommends this setting, it should not be used unless you are fully aware of this performance loss.

    That little excerpt taken from:
    How to harden the TCP/IP stack against denial of service attacks in Windows 2000

    This KB article is still used and is applicable to the Windows 2003 space, but what does this do exactly?

    This will drop all transmissions over TCP/IP down to 576 byte packets. Oh and this is a global setting.
    So, you go to connect up to an iSCSI LUN, and it connects up just fine.
    Your host is working, your storage is working everything is all doozy.

    When you start to try to actually -use- that connection for storage though, you’ll begin to experience exponential latency. This latency will translate into IOPS problems and access to the disk, masking this making it appear to be a disk issue. This effectively cripples your application, yet is hidden so well from the system as a problem without sniffing or using something like mturoute you’d never know it is happening.

  • MTURoute is your friend and will help you determine your current MTU

    With that said, on any systems with iSCSI connectivity, I strongly encourage you to NOT disable this setting, ensuring that EnablePMTUDiscovery is always set to 1

    Thanks for your time!

    CWUG officially moves to Mondays – Meeting this Monday May 19th

    That’s right, the Chicago Windows Users Group is now officially meeting on Mondays.
    Which can have a number of implications, one certainly of which is – we’ll be meeting on Mondays! :)

    This coming meeting we’ll have some great sessions, with the master of Server – Jeff Gettis covering territory on Windows Server 2008 (Should be an amazing time!). Dan Rey presenting on the Windows Easy Transfer Companion (beta) in a hands on lab. And last but not least, Brian Vanderjack with an interesting and compelling session on Project management. This will be Brian’s first time presenting in front of the CWUG audience though he is no shy soul in front of an audience nor let alone in front of students. Brian is not only a professional project manager for a living, PMP but also teaches Project Management courses with the University of Phoenix, so it should be a treat to have a man of his caliber in front of the group of us!

    I look forward to seeing you all at this months CWUG and to have a great time!

    Below are the details of the meeting via the email Blast, and sign up information!

    Thanks to Michael Niehaus for his presentation on the Microsoft Deployment Toolkit 2008 (previously Business Desktop Deployment or BDD 2007) and Bart Tubalinal and Tony Coppa for their presentation on SharePoint at our downtown Chicago meeting! Don’t forget we’re switching to the 3rd Monday evening every month for our in person meeting and will be in Downers Grove for May and June and back in Chicago for July.

    The CWUG Crew

    Chicago is where the heart is

    I get a lot of emails, asking me if I am now based out of North Carolina.

    So, to set the record straight. No, I’m back home in Chicago (though at home sick today).
    I was merely in North Carolina for work for a bit, and had some time to update.

    So, I am alive, home, well (and well, sick)
    Oh, and today is my birthday, so Happy Birthday to me! :)

    I have some additional posts queued up, but those will wait until I’m not as sick.
