From an e-mail I just got from Outlook Tips:
In response to the Windows SharePoint Services and Windows Small Business Server 2003 installation issue, all Windows Small Business Server 2003 (standard and premium edition) customers are eligible to order five free Client Access Licenses (CALs). The offer is available now through February 5, 2004.
This offer is available to all Windows Small Business Server 2003 customers, including those who licensed the product prior to January 5, 2004. This offer includes Retail, Open, and OEM SKUs. To qualify, customers must provide a valid Windows Small Business Server 2003 product ID. Customers are eligible for one 5-pack CAL for each licensed copy of Windows Small Business Server 2003. Customers can choose either user or device CALs.
To order your five free CALs, complete the order form here. I actually have a copy of that server on order for work (once it gets here), so I know I’ll be taking advantage of this.
