Microsoft has provided 20 sample templates to use with Windows SharePoint Services 3.0.

The templates can be downloaded from Microsoft’s Download Center.

Run the download .exe file and extract the templates to a suitable folder on your WSS server (like C:\wss-templates).

From WSS Server, at command prompt run the the following:

cd\
cd C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN
stsadm -o addsolution -filename c:\wss-templates\ApplicationTemplateCore.wsp
stsadm -o deploysolution -name ApplicationTemplateCore.wsp –allowgacdeployment –local
stsadm -o copyappbincontent

To install a specific template, like Knowledgebase, run the following:

stsadm -o addsolution -filename c:\templates\KnowledgeBase.wsp
stsadm -o deploysolution -name KnowledgeBase.wsp –allowgacdeployment –local

Repeat the commands for any other templates you wish to install.

Details of all the templates can be found on TechNet.
