Hello,   First thing I would make sure is that you are on a supported SAS configuration - Windows 10 is only supported on SAS 9.4M3 and SAS 9.4M4. Are you on one of these maintenance levels of SAS 9.4? This means Windows 10 is only supported for SAS Enterprise Miner Client 14.1 (at SAS 9.4M3) and SAS Enterprise Miner Client 14.2 (at SAS 9.4M4). Are you using one of these Windows 10 supported versions of the client?   If yes then can you confirm that the working client on Windows 7 and non-working client on Windows 10 connecting to the same server/environment? If they are then the issue would be on the client side- did you complete all the client side IWA configuration steps documented under "Configuring Client Machines to Use Integrated Windows Authentication" section of the SAS documentation below:   SAS® 9.4 Intelligence Platform: Security Administration Guide, Third Edition http://support.sas.com/documentation/cdl/en/bisecag/69827/PDF/default/bisecag.pdf    It would also help to know what error exactly you get when you attempt to log on using IWA on the failing Windows 10 Client machine if you are on a supported SAS configuration and have completed all the required configuration steps on the client side.   Thanks, Bishal     ...
