Confused About Registering and Troubleshooting SPNs? Help Is On The Way

Kurt Hudson over on the AD documentation team blog has put together a pretty thorough wiki on how to register and troubleshoot Service Principal Names (SPNs).

Check it out; if it doesn’t answer all your questions, or you have suggestions, he’s all ears.
