Essential Exchange

I'm working with a new client and this client is a "wholly owned subsidiary" of another company and is getting ready to be spun off as their own company. One of the things we are doing is configuring their network to be standalone and not part of the corporate Active Directory. That involves...

It was pointed out to me, by a party that shall remain nameless, that I depended in today's earlier post Finding Disk Space Used By Exchange Version 2 , that I ASSumed that msExchCurrentServerRoles would never be higher than 64 and that that was a bad assumption on my part, for reasons that shall...

In July of 2006, I had a blog entry named Finding Disk Space Used By Exchange , and it was quite well received and it worked well for most people. However, it had a few issues: It doesn't work with Exchange Server 2007 because the streaming file was removed from Exchange If a Recovery Storage Group...

The question was recently posed on a mailing list asking whether there was any book that covered the Exchange 2003 security model in depth. The question came up for the poster because of a recent video that is making the rounds on youtube and elsewhere ( http://www.thewebsiteisdown.com ). In that video...

One of the mailing lists I read and occaisionally post on is named ActiveDir. A lot of heavy-hitters in the AD world hang-out around there. I've learned quite a bit by lurking there. A recent poster had wanted to create a few thousand accounts for testing purposes, and have them all follow a certain...

Exchange has caught a lot of crap for publishing the fact that it doesn't work in branch office locations where only Windows Server 2008 read-only domain controllers (RODCs) are available. Exchange simply requires read-write domain controllers. It's a fact. However, it's been a poorly kept...

Over three years ago, a particular publisher in the computer field contracted me to write a book - which I did. They paid me for it, but they chose to never publish it. It was written with Exchange Server 2003 service pack 1 in mind - as you read the text, keep in mind that it was written long before...

As I mentioned in yesterday's post, Wrapping up SLDs and Exchange Server 2007 , anytime after PrepareAD is run, it is too late to run the Domain Rename (rendom) tool. As part of PrepareAD, the Exchange Server 2007 setup tool stamps the Active Directory with a number of server names in GUID and fully...

In Single Level Domains and Exchange 2007 service pack 1 , I commented on the fact that Microsoft was no longer going to support single label domains starting with Exchange Server 2007 service pack 1. Then, in More on Single Label Domains and Exchange 2007 I shared that Microsoft was going to change...

In Problem Between Exchange Server 2007 and MS08-03 , I wrote about a problem introduced by MS08-003 that affected large Exchange environments. Last week, a hotfix was released for this problem. Surprisingly for many, it was actually an Active Directory issue! (Although, I did hear an A/D engineer say...
