"Windows SharePoint Services version 2 templates are not supported in this version of the product."

Today a trusted colleague of mine tried to create a new Team Project in TFS 2008 using the eScrum process templates. We've created around 10 of them in the past with the eScrum process template and everything went fine. Today however, which happened to be a day I'm off sick due to a nasty cold, we get the error "Windows SharePoint Services version 2 templates are not supported in this version of the product." Now why we're getting this now and not in the past, I'm not sure. Something must have changed, or the eScrum template got corrupt on the server. Not sure which is more probable.

After pounding my head against the wall, I ran into "Mike's Blog" (a great read if you have some time) where he gives one solution to our error. Here is my summary.

1) Did all the steps under Step 1), except bounced IIS, of Mike's article. Here were my commands when deleting and uploading the site template.

stsadm -o deletetemplate -title eScrum
stsadm -o addtemplate -filename C:\eScrum.stp -title eScrum

2) I also downloaded the eScum process template, saved the eScrum.stp to .eScrum\SharepointTemplate overwriting the one loaded, and uploaded the new process template labeled as "eScrum with WSS 3.0". To be honest, I'm not sure if this is needed but I did it anyways.

3) Tried to create Team Project called "Vertical Static Content" with new upload I called "eScrum with WSS 3.0" and it worked!

NOTES: During some experimentation, we got this error ""Plugin error text: “TF30272: Template not found on the server”" when trying to create a Team Project after deleting the eScrum template and before adding it back again. This leads me to believe there is something, other than what's in the Process Template, which needs to be on the server when creating Team Projects. Why? I can't understand.
