H I am having this issue on Dell R510. I am installing Windows Server 2008 R2. the installation is successful but when I restart computer the defaultgateway is blank. I have searched the net and also tries registry settings for DefaultGateway on Interface which is already set in registry but still did not show in ipconfig /all any ideas please Javaid Irfan

I would tend to agree. I would go as far as deleting the NIC from device manager, rescan for devices, when the NIC is detected, provide the latest drivers for that specific operating system. You should get the drivers directly from the vendor's web site.Visit: anITKB.com, an IT Knowledge Base.

Thanks Mr. X and JM. I will try this solution today will update regarding results.
