Antivirus Exclusions and Windows

Read-Only Domain Controller Issues

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...

Exchange 2007 and Domain Rename

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...

Exchange Server 2007 and Universal Groups

Do you know what a flat domain is? Do you know what a single-level domain is? You may not even be aware that Active Directory supported single-level domains. If you do - then you've probably run into problems with it in the past. Now there are more...
