Is your OS Windows Server 2008 R2 or Windows Server 2008? If you are using Windows Server 2008 R2, the Intel(R) Network Connections software does not have any drivers for the Intel(R) PRO/1000 P Dual Port Server Adapter. The only drivers available are the basic drivers supplied by Microsoft with the OS.
You could add the ports to a team if you installed one of the newer adapters that has full support for Windows Server 2008 R2 and created a team using one of the ports on the newer adapter. See Is my Intel® Ethernet Adapter supported in Microsoft Windows Server 2008 R2*? for a list of adapters with full support.
