Thomas, You said this is your only server. DC as well. We tried this on a DC and it came crashing down around us. Didn't take long, about 15 minutes after being up it just crashed. When looking around I believe it was said not to do this if the Exchange Server was also a DC. It was several years ago, so the details are fuzzy. We rebooted, changed the registry entries back and cycled again, all was well.
I tried it again and made sure I did the numbers properly and had the same result.
