Having trouble joining Windows 7 to a domain?

If you are having trouble joining Windows 7 to a domain, and receive a odd error message with "Parameter is incorrect" then you are not alone. This issue seems to occur if you have more than 16 characters in the first portion of the domain you are attempting to join.

Microsoft has released a hotfix which addresses this issue on all architectures and you can grab it from : http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=961402&kbln=en-us

On an odd note, the name of the hotfix seems a little bit odd : Windows6.1-KB961402-x86.msu.  It seems odd to name one of the first Windows 7 hotfixes with Windows 6.1.
