Automate Conversion of Your DCs Into GCs
Speed up DC deployment with a simple GC script.
I was recently helping a client deploy domain controllers (DCs)
in about three dozen new offices (frequent flier miles, here I come).
Because each office would eventually house about six hundred employees
and because the company uses Exchange Server 2003, it seemed sensible
to add two or three domain controllers to each office and ensure
at least one of them was a Global Catalog (GC) server. To save time—we’re
talking a total of 75 new DCs—we worked up an automated installations
script to install the domain controllers.
After deploying DCs in two offices, we realized that none of the
DCs we were installing had been made into GC servers. Of course,
we realized this because users were going across the WAN for address
book lookups and were raising heck about the poor performance of
their e-mail clients! We quickly designated a GC in each location
but wanted to fix the problem in our deployment technique.
We were using a Dcpromo answer file to handle the domain controller
promotion process, and a little research turned up the answer: We
simply needed to add the line ConfirmGC = Yes
to the answer file for the DCs that would be GC servers. Seemed
like a nice simple tip for speeding up DC deployment, so I thought
I’d share it!
On an unrelated topic, I’ve
run across an amazing Bluetooth headset you might
want to check out. It’s by Cardo Systems
and it’s called the scala-500. What makes
it cool—other than its slightly less Star-Trek
look than many headsets—is the quality of
its noise cancellation. I swear you can stand in
a high wind and still be heard. If you’re
a Bluetooth geek, it’s worth a look.

hours straight with scala-500.
