As per our translator system, we understand you need a driver for the Intel® SSD DC P3700 for Windows* Server 2008.
The NVMe* driver we have does work for the Windows* Server 2008 R2 version of the operating system and not the R1 version. You can check the requirements in the http://www.intel.com/content/dam/support/us/en/documents/ssdc/data-center-ssds/Intel%20NVMe%20Instal... following link, page 5.
Even though we have not validated the operating system, Windows* Server 2008, please feel free to try the https://downloadcenter.intel.com/download/26451/Intel-SSD-Data-Center-Family-for-NVMe-Drivers NVMe* driver in this link
We'll be waiting for your response.
