When Split-Brain DNS Just Isn’t Possible

Clever post by Geoff Clark on a workaround for OCS when split-brain DNS isn’t an option: http://blogs.technet.com/gclark/archive/2009/05/02/ocs-dns-automatic-configuration-when-split-dns-is-not-an-option.aspx

This could be useful for other applications as well, but I would still push to get split-brain DNS configured if at all possible before falling back to this option as a last resort. While it’s attractive consider the overhead of maintaining and documenting additional DNS zones. Probably not an issue for the admin doing this, but for someone else taking a look at your environment you’ll probably raise some “WTF?” eyebrows.

Doug Lawty expands on Geoff’s idea a bit and uses Dnscmd.exe to work around a GUI limitation to create the exact zone you need: http://blogs.technet.com/dougl/archive/2009/06/12/communicator-automatic-configuration-and-split-brain-dns.aspx

Hi there. My name is Tom Pacyk and this is my small home on the web. I love the intersection of design, technology, and communication, which is a combination that led me to a career in sales and marketing roles at places like Zoom and ServiceNow. They're a bit old now, but I also had the opportunity to publish a couple of books along the way.

Portland, Oregon is home for me, my wife Beth, and our three kids, but I'm actually a Midwestern transplant—I grew up in the Chicago suburbs and went to school at Purdue and Illinois. When I find some free time I'm probably going to concerts, rooting for the Portland Timbers, or working on my Sunshine Burn Photography project.
