Microsoft SQL Server 2008 R2 BPA — Error 1722

A bit of a head-scratcher when trying to install the SQL Server 2008 R2 Best Practice Analyzer. The Baseline configuration analyzer installed just fine, and WinRM / PS2.0 was installed, so no prereqs were missing. However, when running the BPA installer, it would just flash a powershell window and fail. I could run msiexec /i {MSI} SKIPCA=1 to install it, but it wouldn’t initiate. A little bit of digging led me to enable-psremoting cmdlet, which failed […]

Credential prompts in Outlook / Exchange 2013 & 2010 – Updated!

Coexistence between Exchange 2010 and 2013 is fairly new still; so a few bugs is to be expected. This is however a rather large one. Credential prompts in Outlook (I’ve seen this in both 2010 and 2013) is usually an indicator of authentication/virtual directory configuration errors.   What I’ve seen a few times now is that if you have this scenario: User mailbox is on Exchange 2013 User accesses resoruces (public folders or shared mailbox) […]

Setting up single namespace in Exchange 2013

One of the great changes in Exchange 2013 is the simplification of namespaces. Where you in previous versions needed a handful, you can now stick with two. Well, you CAN do it with one actually. The documentation on this is a huge ball of misconceptions and old best practices, so I decided it’ll be worth doing a simple tutorial on how to set it up. Once you know how to do it, it actually is fairly simple. […]

Installing Exchange 2013 CU1 in co-existence

A simple walkthrough of the install of  Exchange 2013 CU1 in a Exchange 2010 environment. This is based on a clean server 2012 install. Just to emphasize one thing first: CAS-arrays are out. CAS in 2013 is just a simple proxy to redirect to the correct user mailbox, so they are no longer needed. Download CU1 from http://www.microsoft.com/en-us/download/details.aspx?id=38176, and extract. Download and install the Microsoft Unified Communications Managed API 4.0, Core Runtime 64-bit from http://go.microsoft.com/fwlink/?LinkId=260990 Download and install […]

Exchange 2013 CU1 released!

Finally! This one has been long in the wait. CU1 enables co-existence with older versions of Exchange (2007/2010), which to be honest most have. Released just now; so not much experience with it so far, but part of the delay has been due to extensive testing, so I imagine it’s all good. Details on the Exchange team blog: http://blogs.technet.com/b/exchange/archive/2013/04/02/released-exchange-server-2013-rtm-cumulative-update-1.aspx And of course the download: http://www.microsoft.com/en-us/download/details.aspx?id=38176 This is a 1.3GB download, so I imagine this is […]

Event ID 36888 – Schannel

I stumble upon this all the time. It’s logged as an error, and it usually comes in bunches, looking like this:   So what to do about this. What is it? Well, nothing. It’s a false alert if there ever was one. It’s basically saying that someone tried to access a website (Exchange website in this case) using an unsecure connection, when a secure connection is required. Http instead of https usually. I did spend […]

0x80200049 Offline Address Book-error

This totally stumped me for a while. I had a few random users getting an 0x80200049 error when downloading the offline address book. I went over everything on Exchange (2010) and everything looked fine and dandy. Even tried resetting the Outlook profile, to no avail. Well, lo and behold; Outlook uses BITS to download the OAB; and if the BITS queue goes full (60 jobs I think), it stops. Intuitive, right. No mention of BITS anywhere, […]

Clean up Java versions – Updated!

REVISED 11/03/13! I’m not alone in having a headache whenever there’s a new Java-version. The old one doesn’t uninstall, the new one might fail to install. It’s a mess more often than not. After spending some time trying to find a good way to clean it all up in an enterprise environment, I decided that there wasn’t a good solution. So, I decided to invent the wheel myself. The result is a powershell script which […]

Exchange ActiveSync features

So I stumbled upon this handy chart: http://en.wikipedia.org/wiki/Comparison_of_Exchange_ActiveSync_Clients Which cured my head-scratching over why I couldn’t see a recovery password for certain devices. Not all Active Sync clients support it. In fact, most don’t. Could be useful to keep in mind when deciding company policy.

Should I upgrade to Exchange 2013

There are nine million Exchange blogs on the web. That’s a fact. So by now you probably know that Exchange 2013 is the bees knees. I won’t bore you with all the technical bits; but I will try to shed some light on the one question that really matters: “Should I upgrade, and if so, when?” Now; Exchange 2010 is a great product. Exchange is really one of those products that hands down get better […]
