The Windows Reseller Option Kit (ROK) is a software distribution option that enables you to order tuned & certified Microsoft server software separately from OEM servers so that you have more flexibility to deliver customised server solutions. Each ROK is another server option that you can specify when you order servers. You can install the appropriate ROK on your customer's preferred server model. Customers still enjoy the same great performance of OEM-tuned drivers for Microsoft Software, because each ROK is carefully matched to a specific server br&. By purchasing your Windows ROK from Lenovo, you have a convenient one-stop-shop for clients, servers & operating systems. You can enjoy a fast, easy method for purchasing affordable servers & options with a Microsoft Windows-compatible operating system. Lenovo & Microsoft work together to ensure that Think Servers & Windows Servers deliver optimal performance & work together seamlessly. Did you know that your Windows Server 2003 including Windows Small Business Server 2003 has reached end of support? We can help you put an upgrade plan in place to reduce costs & increase security. Keep in mind that end of support means that you will no longer receive updates or patches to combat security issues after July 14, 2015. Without updates, your systems are vulnerable to security & compliance issues. If your organization processes Visa & Master Card transactions, for example, you could have problems with the Payment Card Industry Data Security Standard (PCI DSS).
