Windows 7 Windows 7 doesn't see Domain computers but can map drives to them.

Troubleshooting Steps:​

1. Network Discovery Settings: Ensure that network discovery is turned on. This setting allows your computer to see other networked devices. To check:
   • Go to Control Panel > Network and Sharing Center > Change advanced sharing settings.
   • Make sure that "Turn on network discovery" is selected.
   []Check Network Location: Ensure that your network is recognized as a private or domain network, not a public one. Public networks have limited visibility.
   • Go to Control Panel > Network and Sharing Center.
   • Click on the network type and change it to Private or Domain.
   []IP Configuration:
   • Check if your Dell OptiPlex 990 has the correct IP address configuration.
   • Open Command Prompt and type ipconfig /all to view the network configuration details.
   []Flush DNS and Reset TCP/IP:
   • In Command Prompt, run:
     Code:

      ipconfig /flushdns netsh int ip reset netsh winsock reset

   []Restart Network Services:
   • Restart the "Function Discovery Provider Host" and "Function Discovery Resource Publication" services.
     • Press Win + R, type services.msc, find the services mentioned, and restart them.
   []Rejoin Domain:
   • Try removing the computer from the domain and rejoining it.
     • Right-click on This PC > Properties > Change settings > Change > Workgroup.
     • Restart and rejoin the domain.
   []Check Group Policy Settings:
   • Group Policies could be affecting network visibility. Verify if any specific policies are in place that could be causing the issue.
2. Network Sharing Center:
   • Check the Network Sharing Center for any error messages or warnings that could provide more insights into the problem.
