Since Dell servers don't support client OS's, there are times when it simply won't work, however ... Dell's latest driver for 2008R2 can be found here:[URL] Did you try the "hard drive" version or the "Update Package for Microsoft Windows"? If that does not work, then you can use the Broadcom (QLogic) version of the driver (the chips were designed for server use, so even Broadcom/QLogic does not supply drivers for client OS's):[URL] If that doesn't work, before you go out and buy a Windows 7-compatible NIC, you can try one of these: Broadcom NetXtreme I drivers for Windows 7x64:[URL] or and older version of the Dell drivers (you should always try the 'hard drive' version first):[URL]  
Good day! I apologize in advance if this has been answered before, but a searched provided no results. I am trying to install a R210 II server with Windows 7 Professional SP1 64-bit. The OS, unfortunately, cannot be Server 2008 R2 as the client requires SCADA software that is only supported on Windows 7. I would think that the driver designed for Server 2008 R2 should still work on Windows 7 Professional, but when trying to install the driver package (Broadcom NIC) the installer quits stating it is only applicable to Server 2008/R2, etc. Does anyone have an alternative for me? Win7 does install a Microsoft provided driver, but returns a "Device cannot start" error in Device Manager, which I usually find is driver-related.  Thanks in advance!  Dhiren
