Evaluation Version Expired but not really

A friend was building a server and ran into an issue where he was installing a fresh server, put in his trial key and assumed he did everything right, but was getting an error message: "The evaluation version of Microsoft Office SharePoint Server 2007 for this server has expired."

ACTION:
Current user updated MOSS2007 and registered his Volume License Key to the MOSS2007 Installation. Current user tries to Access his "My Site" RESULT: Current user receives following error: "The evaluation version of Microsoft Office SharePoint Server 2007 for this server has expired."

CAUSE:
Insufficient permissions for the groups WSS_WPG, WSS_ADMIN_WPG to the Registry The application pool identity for your WSS/MOSS sites *MUST* be in the "Distributed COM Users" group in order to successfully activate.

RESOLUTION:
We gave group WSS_WPG Read permissions to following registry key HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Office Server\12.0 We gave group WSS_ADMIN_WPG Full permissions to the same registry key HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Office Server\12.0 We added application pool Account ("dcomcnfg.exe") to the Distributed users We rebooted the server

By the way, these are the kind of blog posts that I like to run into when searching for answers on the Internet. They kind of feel like a KB article. Let's say you're an IT guy, but don't know what to blog about. You run into an issue, you solve it. Ideal and perfect for a post. Short and sweet. Great reference for you and the rest of the world. If they don't need the info, the don't need to read it.
