Were you accessing your 2008 Servers with SBS 2003 R2 CAL's?
Well, it's time to upgrade!
LAST YEAR, we offered this:
============================
As a benefit to our clients with SBS 2003 R2 CALs (yes, you need to have 2003 R2 licenses, not just SBS 2003), we are providing a special offer right now. For those with SBS 2003 R2 CALs, we are offering access rights to Windows Server 2008 servers (you will need to purchase your Windows Server 2008 server licenses) added to your SBS 2003 R2 domain until May 31, 2009. That’s right, we are allowing you to add Windows Server 2008 servers to your SBS 2003 R2 domains and use your SBS 2003 R2 CALs to access them until May 31, 2009 without needing to either purchase Windows Server 2008 CALs or to have SBS 2008 CALs. At that point (May 31, 2009), you will need to decide if you wish to continue to have Windows Server 2008 servers in your SBS domain. If you do, then you will need to either add Windows Server 2008 CALs to do so or upgrade your SBS CALs to SBS 2008 CALs to do so.
This means that we are giving a 12 month (June 2008 – May 2009) licensing reprieve to those with SBS 2003 R2 CALs who want to use Windows Server 2008 servers in those SBS 2003 R2 domains. Without the introduction of this special offer, anyone who wanted to introduce a Windows Server 2008 server to their SBS 2003 R2 domain today would need to purchase Windows Server 2008 CALs at that time since SBS 2008 is not available yet today. Now they will not need to purchase those Windows Server 2008 CALs today to introduce those Windows Server 2008 servers into their SBS 2003 R2 domains and will have until May 2009 to either upgrade to SBS 2008 CALs or purchase Windows Server 2008 CALs.
Now for those of you with Software Assurance on your SBS 2003 servers and CALs, there will be no decision to make in May, 2009 because your SBS 2003 R2 CALs will automatically receive SBS 2008 CAL rights as soon as SBS 2008 is released, so you’ll be good to go whether you upgrade your SBS Server to 2008 or stay at SBS 2003 R2. It’s all included in your upgrade protection rights granted in your Software Assurance benefits.

===========================
Since we are now into the month of June 2009, it is time for you to make that decision to upgrade your entire SBS 2003 R2 install to SBS 2008 or downgrade those 2008 boxes to 2003.
