The Intel® SSD DC P3700 Series and other Intel® NVMe SSD's are not supported with Microsoft Windows Server 2003*. We recommend you to install and use these drives in systems with one of the supported operating systems, which include Microsoft Windows Server 2008 R2*, Windows Server 2012 R2* and Windows Server 2012*. For more details about the System requirements, please check the following document:
Unfortunately, Intel does not provide NVMe SSD drivers for Windows Server 2003*, and since Microsoft already announced Windows Server 2003* extended support has ended, we do not expect this to change in the future.
If you need to use Windows Server 2003*, you might consider using SATA Intel® Data Center SSD's, or other storage solution compatible with this configuration.
