to a single organization, but Microsoft Dynamics CRM 4.0 Professional can be installed 
on more than one computer in the same deployment.

Licensing
A Microsoft Dynamics CRM 4.0 deployment operates by using a single license key. Unlike earlier 
versions, Microsoft Dynamics CRM 4.0 no longer requires additional license keys to be added 
when changes are made, such as adding more client access licenses (CALs). The single license 
key contains the Microsoft Dynamics CRM version, server license, and the CALs.  
You can view and upgrade a license in Deployment Manager. 
Client Access License Types
Microsoft Dynamics CRM 4.0 has the following CAL types: 
• Read-Only. Clients who use this license type can only view records and data in Microsoft 
Dynamics CRM 4.0. They cannot modify records or data. A user configured with this 
license type consumes a CAL. 
• Administrative. Clients with this license type can modify records in data that is located in 
the Settings area. However, these clients cannot view or modify records and data in the 
Sales, Marketing, or Service areas. A user configured with this license type does not 
consume a CAL. 
• Full. Clients who use this license type have full functionality and are only limited by 
security roles and privileges. A user configured with this license type consumes a CAL. 
You can view and modify client-access license types for each user in the Users area of the 
Settings area in the Microsoft Dynamics CRM Web client. 
What’s New in Microsoft Dynamics CRM 4.0? Microsoft Dynamics CRM 4.0 includes several new features that offer flexibility, scalability, and 
ease of use.  
Multi-Tenancy
Earlier versions of Microsoft Dynamics CRM Server were a single-organization solution. Microsoft 
Dynamics CRM 4.0 lets you host multiple organizations in a single deployment. This feature is a 
great benefit for hosted solutions or businesses that require a separation of data inside the 
organization. Microsoft Dynamics CRM 4.0 now implements two types of databases: 
•  A single configuration database that stores metadata and location information for all 
organizations. 
•  One or more organization databases.
