I have just created a Wiki article, Troubleshooting Domain Join Error Messages (http://social.technet.microsoft.com/wiki/contents/articles/troubleshooting-domain-join-error-messages.aspx). This article details some of the common error messages when performing a domain join of a client machine. It is in a table format and includes the error message as well as possible resolution steps.
Please take a look and let us know what you think. You can leave a comment or edit the Wiki article directly.
