CRM Debug Information Page
Each CRM installation has an out-of-the box ASPX page that contains basic information regarding your CRM (verified for CRM 4.0 and CRM 2011) installation.
If you refer to the following URL:
https://ServerName:Port/OrgName/home/home_debug.aspx (replace ServerName, Port and OrgName to reflect your installation)
You will receive information regarding DataSource, Component Version Numbers, OrganizationID, etc.
