No, I’m actually not talking about the crazy SNL skit and follow-up with Mark Walhberg!

No, I’m talking about Exchange and its IO going through the roof when you use Entourage for the Mac in a typical Exchange environment.

Microsoft has a KB329067 Article which relates to this issue with some ‘guidance’ on how to correct it, but exactly how far you take it is another matter.

Information about performance issues that occur when you use POP3, IMAP, or WebDAV clients, such as Entourage, after you move mailboxes in Exchange Server 2003 or in Exchange 2000 Server

Basically, what you’ll get from this article is this:

1. Start Registry Editor.

2. Locate and then click the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeWEB\DAV

Note By default, the DAV key is not in the registry. You will have to create it yourself.

3. On the Edit menu, click Add Value, and then add the following registry value:

Value name: MaximumResponseSizeInBytes
Data type: REG_DWORD
Radix: Decimal
Value data: value

For example, if you decide to increase this value to 500 megabytes (MB), use the following calculation:

1024 * 1024 * 500 = 524288000 (Decimal) = 1F400000 (Hexadecimal)

Enter the results of this calculation in the Value data field. In this example, you would enter 524288000 (Decimal) or1F400000 (Hexadecimal). Remember that the configurable range for this registry key is 1 MB to 1 gigabyte (GB). Better results occur if customers set it to a value of 500 MB or a higher value, such as 800 MB.
NoteWe recommend that you set the value back to the default value or to a lower value after the content conversion issue subsides in your organization. The default value of this registry key is 128 MB. We also recommend that you set correct messages limits and mailbox size limits on your Exchange server to prevent performance issues.

4. Exit Registry Editor.

I can only read this particular KB article so much before I say “Hmm, but what actually works?”

Here is a solution which is tried, true, and used and tends to work most of the time.

Modify this Key to this value:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeWEB\DAV

Value name: MaximumResponseSizeInBytes

Decimal: 838860800

What this does is set it to 800MB, as opposed to the ‘referenced’ 500MB example.

In a majority of all circumstances this will take considerable strain off of both your Exchange server as well as your underlying storage.   The end result is, Marky Mark and the Entourage Bunch won’t cause Exchange to Spike and cause severe latency issues for your users.

I think that calls for a definite win situation!

Kind of like how Andy wins in this situation…!

In light of a recent post by Kate where she analyzes and comments on her Google Analytics, I’ll do the same (this also applies to my respective WordPress Stats :))

So, lo and behold the following – Top keywords people find this blog under!

• 70-432, 70-656, 70-652, 71-432 – Apparently, a lot of people are searching for a lot of MS Certification exams.  And to that point, a majority of the keywords tend to be active based upon specific Cert numbers
• pciven_8086&dev_4227 – Oh, that old chestnut!  You’d be surprised how often that comes up! :)
• ontap 7.3, data ontap 7.3 – Apparently, I’m one of the best sources for material on NetApp’s Data ONTAP 7.3, and I’ve not even touched the surface of the types of things you can do, in general let alone in blog posts.  I have a whole backlog of material I’ve yet to touch, so it’s surprising the following I have as it stands, I fear for the future! :)
• osql shrink database – This one in particular is huge.   How often are you looking to shrink a database using osql, and you don’t remember how? I wrote it for me, and to share the wealth, luckily it looks like the wealth is being shared!
• mcts hyper-v – And other Hyper-V topics.   Seems my Hyper-V rig was good enough to stir up conversation and hits around Hyper-V.  If I were to leverage this more, this could be an even more compelling story, though I feel like almost all of Virtualization is ‘yesterdays news’,  lets find the next new tomorrow item, Virtualization is like 4 tires on a car – Ofcourse you have it, now lets make it go faster!
• defconnectopts – Yea, you sexy little expression you! Damn do I get hit up on this quite often! Get your mad defconnectopts on!
• christopher kusek – Wow, people searching for me, and finding my blog! Who woulda thunk it! :)
• enablerpctunnel, rpc over http outlook 2007 – This and variations of this are quite possibly my most hit articles ever.  I wrote this a few years ago, and it’s still references (quite regularly) to this day, to help people get Outlook 2007, Vista, RPC over HTTP.. etc all working together – So go to town! I wish more people commented on it for the volume who get helped :)
• msde shrink database – This one, similar to the osql one is an especially important one.  “No-one uses MSDE anymore.” Yes, you are correct, except for when they do. :) So, I’m glad this particular item has been able to help out so many as well!

So, while this may not be quite as cool as Kate’s post, it is nonetheless a fairly accurate representation of the type of major hits people come across my blog under :)

Certainly, if you think there is certain material I ought to be covering (in any of these areas or more) don’t hesitate to let me know :) I have content in the backlog meaning to get its way out there, it’s just a matter of time to compose and deliver it! :)

I’ve been sitting on this for awhile (Hey, i’ve been busy and this isn’t free, so lower priority!)

Cisco is kicking off the Beta Exam for the CCIE Wireless!

Cisco is soliciting beta candidates for the soon-to-be-launched Cisco CCIE Wireless Written Exam. We are looking to create a highly qualified group of professional- and expert-level Wireless Networking Engineers who are willing to dedicate three (3) hours to take the beta exam.
The CCIE Wireless certification, to be launched later this year, will validate that a professional has the expertise to design, manage, and support mission- and business-critical wireless networks, as well as the job skills and technical knowledge required of an expert-level network IT practitioner. This written exam is the first step in obtaining the CCIE Wireless certification. Successful candidates will have mastered broad theoretical knowledge of wireless networking and demonstrated a readiness for the CCIE Wireless lab examination.
Be one of the first professionals in wireless to get a peek at the new CCIE Wireless exam!

• Location: Pearson Vue Testing Centers, Worldwide
• Registration Date: 7-Oct-08
• Last Test Date: 14-Nov-08
• Cost: US$50
• Exam Number/Name: 351-050 CCIE Wireless Beta Written Exam

So, you wireless Guru’s and masters out there, Go check this out!

I would if I cared about Wireless anymore, did it for a living or otherwise.  But that ship has sailed and well, I don’t feel like forking up $50.00 at the moment for a test I don’t have time to take for an No Strings Attached CCIE Certification! ;)

If I change my mind, I’ll let you know, but I don’t think I’ll have the time anytime soon!

Hey everybody! A few updates which will directly impact you that you should know about!

First of all, I’ve updated the Free Testing Archive to age old invalid certs and include new certs – So check it out!

Next of all, we’re getting closer to the availability of the NS1-501 SAN Exam from NetApp.  Prometric has the details published just not available to schedule a test yet.  That should change in the next week or so.   This is an entirely new exam so any old ‘test data’ which one has for it, likely won’t be valid anymore.    I’ll need to rewrite the study guide I wrote for the original version.

Next, welcome the first in a series of .NET 3.5 beta exams!

71-563: Pro: Design & Dev Windows Apps Using MS.NET Framework 3.5 – October 13, 2008 – October 30, 2008 (Code: DW897)
