If you have recently tried to upgrade from SBS 2003 RTM you might have hit a minor issue - we did not have the premium tech CDs available. While we can not promise them to be available today, the problem is being worked on and the issue will be resolved. However, the supply of CDs is limited, so if you plan to do this, order the CD now and save the CD for when you want to upgrade. The URL with the information can be found at http://www.microsoft.com/windowsserver2003/sbs/downloads/sp1/default.mspx . Standard users will still just need to download the SP1 bits. Premium users will need to download the SP1 bits AND order the Microsoft Windows Small Business Server 2003 Premium CD3 which contains the bits needed for ISA. An update will be posted on April 30, 2007. thanks David Technorati tags: SBS 2003 , Service Pack 1 , ISA 2004
