What version of SharePoint am I running?

1. Find out your server name and the port number for SharePoint Central Administration. In my case its moss2007vm1 and 41819.

2. Go to the Settings.aspx page in the Layouts folder - i.e. http://moss2007vm1:41819/_layouts/settings.aspx

3. Look for Version under Site Information. In my case its 12.0.0.6219.
