Dear Imatinkerer,
Thank you for contacting Intel.
You are getting the error message because our latest driver pack doesn't support the Intel® PRO/1000 MT Server Adapter. This adapter model uses the driver available in MS Windows* 7 (In-box driver). Please refer to website below for more information on adapters with Windows 7 driver support:
Network Connectivity — Is My Intel® Ethernet Adapter Supported in Microsoft Windows 7*?
Hope this helps.
Sincerely,
Sandy
