Q: Where can I obtain Windows Small Business Server 2003 R2 (SBS 2003 R2)?
A: SBS 2003 R2 will be available in all channels (OEM, Open, Retail, System Builder) once it becomes generally available. Each channel has slightly different lead times and delays; contact your channel partner for details. Most channels will continue to carry SBS 2003 for some time after the SBS 2003 R2 launch.
Q: How long will SBS 2003 remain on the market once SBS 2003 R2 is released?
A: Most resellers or channel partners continue to carry stock keeping units (SKUs) for earlier software versions. Microsoft typically removes older versions of the SKUs within a year after the new version launch. SBS 2003 R2 will follow these normal policies. Note that these policies differ by channel (OEM, Open, Retail, System Builder), so check with your software vendor for additional information.
